Answer: Probability that they will both occur is 25%.
Explanation:
Since we have given that
There are two non simultaneous events.
Probability of each event = 50%
Since both are independent to each other.
Let A and B be two events.
We need to find the probability that they will both occur i..e P(A∩B).
As we know the rule of independence of events:

Hence, Probability that they will both occur is 25%.
