Question

A bead is chosen randomly from a cloth bag. If 40% of the beads are spheres, and 30% of the spheres are blue, what's the probability of choosing a blue sphere?

Answer 1

Answer: 12%

Explanation:

To find the probability of picking not only a sphere but one that is blue as well, you need to multiply the probabilities of both events because this would show the probability of getting the second event if the first is gotten:

= Probability of sphere * Probability that sphere is blue

= 40% * 30%

= 12%
