Question

A jar has 9 pennies.

Answer 1

Answer:

3/40

Step-by-step explanation:

Probability (Quarter 1st) :

⇒ Number of quarters / Number of coins

⇒ 5 / 9 + 3 + 8 + 5

⇒ 5/25

⇒ 1/5

============================================================

The coin is not replaced.

Probability (Penny 2nd) :

⇒ No. of pennies / Total - 1

⇒ 9 / 25 - 1

⇒ 9/24

⇒ 3/8

==========================================================

Probability (both) :

⇒ 1/5 × 3/8

⇒ 3/40
