Suppose a bag contains 9 silver coins and 1 bronze coin. what is the probability of randomly choosing a silver coin, not replacing it, and then randomly choosing a bronze coin? a. 4/5 b. 8/45 c. 1/10 d. 28/45

First, find the probability of choosing a silver coin. There’s 10 coins total and 9 are silver, so 9/10 chance.

Second, find the probability of choosing the bronze coin after taking out and not replacing a silver coin. There’s now only 9 coins and 1 bronze coin, so 1/9 chance.

Third, when you’re finding probability of multiple events happening you have to multiply the probability of each individual event to find the probability of the chance of all these events happening how it’s described.

9/10(1/9)
9/90
1/10

Answer is C. 1/10
