In a class of 29 children, 15 like history and 21 like math. They all like at least one of
the two subjects.
What is the probability that a child chosen at random from the class likes math but
not history?
Answers
Answer:
14/29
Step-by-step explanation:
The probability that a child chosen at random from the class likes math but not history is 14/29 or 0.4827.
It is given that the in a class of 29 children, 15 likes history and 21 like math.
It is required to find the probability that a child chosen at random from the class likes math but not history if they all like at least one of the two subjects.
What is the Venn diagram?It is defined as the diagram that shows a logical relation between sets.
The Venn diagram consists of circles to show the logical relation.
We have:
Total students in a class = 29
First we have to find the number of students who likes both subject for this we have draw a Venn diagram shown in the picture.
From the Venn diagram number of students who likes both = 7
And number of students likes only math = 14
Hence, the probability will be:
[tex]p = \frac{14}{29}[/tex] ( because total number of students is 29)
or P = 0.4827 or 48.27%
Thus, the probability that a child chosen at random from the class likes math but not history is 14/29 or 0.4827.

Juhi sells a washing machine for Rs 13500. She loses 20% in the bargain . What was the price at which she bought it
Answers
➽ Let the cost price of the washing machine be a variable and apply the condition that the loss Juhi faced was 20% of the cost price, i.e., Rs. 13,500 is 80% of the cost price to form an equation. Solve the equation to get the answer.
Solution :➽ The selling price of the washing machine after bargain = Rs 13, 500
➽ percentage of loss she had in the bargain = 20 %
let the price paid by juhi be x
➽ Now interpreting the statement in the question
in mathematical form we get :
[tex] \implies[/tex] loss = Rs 2 / 10 × 2
[tex] \implies[/tex] Loss = Rs 2 / 10 × x
➽ According to the simple marketing norm, if we subtract the loss from the buying price, we will be getting the selling price for which Juhi sold the washing machine.
Profit / loss = purchasing price - Selling price
Substituting the values the above equation, we get;
[tex] \implies[/tex] 2 x / 10 = x - 13500
[tex] \implies[/tex] 2 x / 10 = x - 13500 / 2
On cross-multiplication, we get;
2 x = 10 ( x - 13500 )
[tex] \implies[/tex] 2 x = 10 x - 13500
[tex] \implies[/tex] 8 x = 13500
∴ x = 13500 / 8 = 16875
∴ Hence the price that Juhi paid for buying the Washing machine was Rs. 16,875.Additional information :
❑ Don’t get confused and take the 20% of the selling price while you solve, as you should be very clear that the percentage loss or profit are terms related to the actual pricing not to the price for which you crack the deal. The other way of thinking of this is that the selling price might vary from buyer to buyer depending on the bargain they put in, but the percentage should be defined from a fixed mark so that you can easily handle it. The reason that most products in the market have an MRP tag on it making it easier for all the sellers to handle their margins.

q2 + 69 + 9 = 0
Answers
Answer:
the value of q = -3
Step-by-step explanation:
The computation of the equation is shown below:
Given that
q^2 + 6q + 9 = 0
q^2 + 3q+ 3q + 9
q(q + 3) + 3(q + 3)
(q+3) (q+3)
q = -3
Hence, after solving it the value of q = -3
Most states and Canadian provinces have government-sponsored lotteries. Here is a simple lottery wager, from the Tri-State Pick 3 game that New Hampshire shares with Maine and Vermont. You choose a three-digit number; the state chooses a three-digit winning number at random and pays you $500 if your number is chosen. Because there are 1000 three-digit numbers, you have probability 1/1000 of winning. Taking X to be the amount your ticket pays you, the probability distribution of X is Payoff X Probability: $0.00 0.999 What is your average payoff from many tickets
Answers
Answer:
For many(n) tickets, the average payoff is 0.5n, in which n is the number of tickets.
Step-by-step explanation:
1/1000 chance of winning.
This means that there is an 1/1000 probability of you earning $500.
1 - 1/1000 = 999/1000 chance of losing.
In this case, you earn nothing.
What is your average payoff from many tickets
[tex]A = \frac{500*1}{1000} + \frac{0*999}{1000} = \frac{500}{1000} = 0.5[/tex]
Your average payoff from a ticket is 0.5. So for many(n) tickets, the average payoff is 0.5n, in which n is the number of tickets.
