Respuesta :

Answer:

0.0809

Step-by-step explanation:

The jar contains 18 Pennies, 13 Dimes, 18 Nickels and 13 Quarters

Total number of coins = 18+13+18+13 = 62 coins

The probability that you reach into the jar and randomly grab a nickel and then, without replacement, another nickel?

At first, there are 18 nickels contained in the 62 total coins

After picking a nickel, there are 17 nickels contained in 61 total coins now.

This probability = (18/62) × (17/61) = 0.0809
