Question

suppose you like to keep a jar of change on your desk. currently, the jar contains the following: 8 pennies 13 dimes 12 nickels 22 quarters what is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, a dime? express your answer as a fraction or a decimal number rounded to four decimal places.

Answer 1

Explanation:

12 nickels out of (8+13+12+22 = 55) coins 12/55 chance of nickel

now there are only 54 coins and 13 are dimes : 13/54 chance of dime

12/55 * 13/54 = 26/495 = .0525 chance
