I'm very new to statistics as well as this forum, so please bear with me.

I've tried solving this for about 30 minutes now and I've made pretty much 0 progress on it. The question is:

Suppose that evens A and C are mutually exclusive. P(not A)=0.7, P(CB)=0.4, what are the maximum and minimum values for P(not C)?

An answer is helpful, but what I'm really looking for is detailed steps on how to approach, simplify, and solve this problem.

Thanks in advance.
