Answer:
Step-by-step explanation:
She has 5 dimes, 2 pennies, and 3 nickels in her pocket.
So 5+2+3 = 10 coins total.
For the first coin is a dime, the probability = number of dimes/total number of coins
= 5/10
= 1/2
After that, 9 coins are left with 4 dimes, 2 pennies and 3 nickels.
For the second coin is a penny, the probability = number of penny / total number of coins
= 2/9
Combining the above, probability that the first coin is a dime and the second coin is a penny
= 1/2 * 2/9
= 1/9
