Question

There are 10 cups placed on a table face down. Beneath each cup is one coin. Together, there are 5 quarters, 2 nickels, and 3 dimes. One cup is randomly selected, replaced, and then another cup is selected. What is the probability of getting a quarter then a nickel?

The options are
- 3/20
- 1/10
- 1/9
- 7/10
​

Answer 1

1 / 10

Explanation:

Prob of getting a quarter on the first draw = (5/10)

Prob of getting a nickel on the second draw = (2/10)

So......the overall probability is (5/10) (2/10) = 10 / 100 = 1 / 10

Took the test and this is the correct answer
