Suppose that 5 years of service, 30% of computers have problems with motherboards (MB), 40% have problems with hard drives (HD) and 15% have problems with both MB and HD. What is the probability that a 5-year old computer still has fully functioning MB and HD

0.45

Explanation:

Probability of bad motherboard(MB) = 0.30

Probability of bad hard-drive(H) = 0.40

Probability of bad motherboard and hard-drive (MB and H) = 0.15

P(MB U H)= P(MB) + P(H) -P(MB and H)

=0.30+0.40-0.15=0.55

Probability that a 5 year old computer would have no problems of motherboard and hard-drive =

1-P(MB U H) = 1-0.55= 0.45

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
