A machine part may be selected from any of three manufacturers

with probabilities p1 = 0.25, p2 = 0.50, and p3 = 0.25. The probabilities that it will

function properly during a specified period of time are 0.2, 0.3, and 0.4, respectively,

for the three manufacturers. Determine the probability that a randomly chosen

machine part will function properly for the specified time period.

Is it conditional probability related?
