Prob (M/S)

Step-by-step explanation:

If we have two events, let's call them A and B, the probability of A given B can be write as:

Prob (A/B)

Then, if S is the event that a randomly chosen store is having a sale and M is the event that a randomly chosen store has marked up their prices in the last six months, we can say that:

Given that the store is having a sale, the probability that a randomly chosen store has marked up their prices in the last six months is equal to given S what is the probability of M or what is the probability of M given S, so we can write that as:

Prob (M/S)
