the one strip is a whole fraction strip and the others are just part of the whole
B. 9*10^16 (because in question give it)
B. 3*10^9 (because answer to first question is divided by seconds in one year (365*24*60*60).
Answer:
0.85
Step-by-step explanation:
Given two events A and B, the probability that either A or B occurs is given by:

where
the probability that A occurs
is the probability that B occurs
is the probability that both A and B occur at the same time
In this problem, we know the following facts:
is the probability that the car requires an oil change
is the probability that the car requires a brake repair
is the probability that the car requires both an oil change and brake repair
Therefore, the probability that either o (car requiring oil change) or b (car requiring brake repait) occur is:
