Two conditions under which we can assume that the sample means follow a normal distribution are as follows:
1). If the sample size is large enough, n greater than or equals 30, the sampling distribution is approximately normal regardless of the shape of the population.
2). In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean.

Add 2 to both sides so it becomes:
V < 22
Step-by-step explanation:
At first we can find AC
then we can find m<A and m< C
or, m<C and then m< A
m<B is already given in the question so there is no need of finding it.
