Answer:
P(AC∪B)=0.9+0.35=1.25
Step-by-step explanation:
I am not sure if A = {E1, E2} and others are combined probability, but try either way and see if it works or not. Are events combined or mutually exclusive?
1. Find P(Ac ∪ B)
Use probability formula (Mutually exclusive): P(A∪B)=P(A)+P(B)
2. Find P(A) and P(B) and P(C)
P(A) = 0.1 * 0.15 or try 0.1 + 0.15
P(A) = 0.0015 or 0.25
P(B) = 0.15 * 0.2 or try 0.15 + 0.2
P(B) = 0.03 or 0.35
P(C) = 0.1 * 0.25 * 0.3 or try 0.1 + 0.25 + 0.35
P(C) = 0.0075 or 0.65
P(AC) = 1.125*10^-5 or 0.9
3. Find answer
P(AC∪B)=P(AC)+P(B)
P(AC∪B)=1.125*10^-5+0.03=0.03
OR
P(AC∪B)=0.9+0.35=1.25

Explanation:
I thought about it, and just flipped the numbers. I use an online grading system to check it, so I am pretty confident I am correct.
