The probability that she will pick a nickel or dime is 1/2

Step-by-step explanation:

Tiara has 4 nickels, 6 pennies, 4 dimes and 2 quarters in her pocket.

In total, she has 16 coins in her pocket. That is:

4 + 6 + 4 + 2 = 16 coins

The probability that she will pick a nickel or dime is the sum of the probability that she will pick a nickel and the probability that she will pick a dime.

The probability that she will pick a nickel is the number of nickels divided by the total number of coins, that is:

4/16 = 1/4

The probability that she will pick a dime is the number of dimes divided by the total number of coins, that is:

4/16 = 1/4

Hence, the probability that she will pick a nickel or dime is:

1/4 + 1/4 = 2/4 = 1/2

The probability that she will pick a nickel or dime is 1/2.
