Answer: P (A or B) = 0.53
Step-by-step explanation:
P(A or B) is the probability where one of the events happened but not both of them.
Probability of event A = 0.45
Probability of not event A = 1 - 0.45 = 0.55
Probabiity of event B = 0.80
Probability of not event B = 1 - 0.80 = 0.20
Then, the probability that one customer buys a burger but does not buy fries is:
P1 = 0.45*0.20 = 0.09
Probability of purchasing fries but not a burger:
P2 = 0.80*0.55 = 0.44
P (A or B) = P1 + P2 = 0.09 + 0.44 = 0.53
