Question

Hi guys, any help would be appreciated. Walk me through it?
A container holds 15 pennies, 8 nickels, and 10 dimes. You will randomly select two coins without replacement.

Use the tree diagram to answer the following:
How many ways can you select the coins?
How many ways can you select exactly 1 nickel?
What is the probability that you select 2 pennies?
What is the probability that you select a dime and then a penny?
