Answer:

There are 8 quarters in the jar.

Step-by-step explanation:

There are 20 coins in a jar.

Each coin is either a nickel or a quarter.

The probability of selecting a nickel is 0.6

Let's assume there are x number of nickels

The probability of selecting a nickel coin is [tex]\frac{x}{20}[/tex] = 0.6

So x = 0.6 × 20 = 12

Hence there are are 12 nickel coins and 20 - 12 = 8 quarter coins.
