Probability of 2 Independent Events

Example – Two Independent Events

Example Gerardo has 9 dimes and 7 pennies in his pocket. He randomly selects one coin, looks at it, and replaces it. He then randomly selects another coin. What is the probability that both coins he selects are dimes? A – First coin is a dime B- Second coin is a dime
