Question 505864: The probability that a PC and a printer function without fail for the first year of guarantee is 0,95 and 0,60 respectively. Assuming the probabilities are independent, calculate the probability that within the year only one of them breaks down.

You can put this solution on YOUR website! The probability that a PC and a printer function without fail for the first year of guarantee is 0,95 and 0,60 respectively. Assuming the probabilities are independent, calculate the probability that within the year only one of them breaks down.
---
P(both break down) = 0.4*0.05 = 0.02
---
P(neither breaks down) = 0.95 = 0.60 = 0.57
----
P(one will break down) = 1 -[0.02+0.57] = 1 - [0.59] = 0.41
--------------------------------
