WGU C955 OA EXAM 2025/2026
A man will have enough money to pay the rent if he gets 100100 hours
of work at job A or if his wife earns enough money to pay the rent for
both of them. If we want to find the probability that this couple will be
able to pay the rent, what is the relevant piece of information to know
when deciding whether to use the formula P (A or B) =P(A)+P(B) or P
(A or B) =P(A)+P(B)−P (A and B)?
Answer- Whether there is any possibility of his wife earning enough
money and his getting 100 hours of work at job A.
