Find the probability. There are six nickels and seven dimes in your pocket. You randomly pick a coin out of your pocket and then return it to your pocket. Then you randomly pick another coin. Both times the coin is a nickel. a. 6/13b. 2/7c. 5/16d. 3/19

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 .    

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
