Question

A stereo manufacturer places a rush order for two different types of wires for its speakers: Fat and Thin. Experience has shown that there’s an 80% chance that at least one of the orders will arrive within the week.

Furthermore, if the Thin insulation arrives within a week, there’s a 40% chance that the Fat will arrive within a week.

Lastly, if the Fat arrives within a week, there’s a 60% chance that the Thin will arrive within a week.

What is the probability that the Fat wire arrives within a week?

What is the probability that the Thin wire arrives within a week?
