Homework Help: Math

Posted by Anna on Friday, November 6, 2009 at 9:00pm.

At a quality control checkpoint on a manufacturing assembly line, 8% of the items failed check A, 10% failed check B, and 2% failed both checks A and B.

a. If a product failed check A, what is the probability that it also failed check B? b. If a product failed check B, what is the probability that it also failed check A?
c. What is the probability that a product failed either check A or check B?
d. What is the probability that a product failed neither check A nor check B?

I am not good with probability and the percentages are really throwing me off. Any help would be great.

Prob(B given A)=Prob(A,B)/Pr(A)
= .02/.08=.25
