Michael has 3 quarters, 2 dimes, and 3 nickels in his pocket. He randomly draws two coins from his pocket, one at a time, and they are both dimes. He says the probability of that occurring is 1/4
because 2 of the 8 coins are dimes. Is he correct? Explain.

Answer:

The events are dependent. The size of the original sample space is 8. It changes to 7 after the first dime is chosen. The probability of picking the first dime is 2/8. The probability of picking the second dime is 1/7 ,To find the probability of the compound event, multiply the probabilities.
