Question

a piggy bank contains 20 quarters, 15 times, 7 nickels, 8 pennies. after shaking 6 quarters out of the bank, what is the probability that the next coin randomly shaking from the bank will be another quarter

Answer 1

14/49 however I’m not American so I’m assuming 15 times is a coin there

Answer 2

7/22

Explanation:

Let's itemize the contents of the piggy bank:

Quarters = 20

Times = 15

Nickels = 7

Pennies = 8

Total in the piggy bank= 50.

After Shaking 6 quarters out of the bag, the remaining content in the bag = 50 - 6

= 44.

Pr ( next coin will be quarter) = 14 / 44

= 7/22
