Venn Diagram Probability word problem example

A manufactured component has its quality graded on its performance, appearance, and cost. Each of those three characteristics is graded as either pass or fail. There is a probability of 0.40 that a component passes on both appearance and cost. There is a probability of 0.31 that a component passes on all three characteristics. There is a probability of 0.64 that a component passes on performance. There is a probability of 0.19 that a component fails on all three characteristics. There is a probability of 0.06 that a component passes on appearance but fails on both performance and cost.

a) What is the probability that a component passes on cost but fails on both performance and appearance?

b) If a component passes on both appearance and cost, what is the probability that it passes on all three characteristics?
