Answer:
Step-by-step explanation:
We have been given that there are six nickels and seven dimes in your pocket. We are asked to find the probability of getting a nickel coin both times with replacement.
Let us find probability of getting a nickel in one pick.
There are 6 nickels and total coins are 6 nickels plus 7 dimes that 13 coins.
Since the coin is returned back in the pocket, so probability of choosing 2nd nickel will be 
.
Since both terms are independent, therefore, probability the required probability will be product of and .
Therefore, our required probability would be .
1 mile.

Answer:
Therefore there total of 39 children presented in group of people who attended a ball game.
Step-by-step explanation:
Given:
Total people present=52 .
And there are 3 times children as adults
To Find:
No.of Children Present in Group.
Solution:
<em>Consider 'x' be the children and 'y' be Adults presented in group.</em>
<em />
So there are total of 52 people.
Therefore Equation becomes,
x+y=52.
And also there are 3 times children presented in group as adults were.
So
Children=3 times adults
i.e.x=3y
Using in above Equation we get ,
x+y=52
3y+y=52
4y=52
y=52/4
y=13
Hence there are 13 adults presented in group
So ,
No.of Children=x=3y
=3(13)
=39
No.of.Children =39
