You are spinning a spinner labeled 1-5 and you choose a marble out of the bag of 7 marbles, 2 are blue, 3 are red, 1 is green and 1 is black. what is the probability of the following: p(spinning a 3 and choosing a red) leave your answer as a unreduced fraction

Step-by-step explanation:

It has been given that you are spinning a spinner labeled 1-5 and you choose a marble out of the bag of 7 marbles, 2 are blue, 3 are red, 1 is green and 1 is black.

The probability of spinning a 3 would be: .

The probability of choosing a red would be:

Since both events are independent, so probability of spinning a 3 and choosing a red marble would be probability of spinning a 3 times probability of choosing a red marble.

Therefore, the probability of spinning a 3 and choosing a red marble would be .

i believe b is the answer
