he events are not independent
How to determine if they are mutually exclusive?
The given parameters are:
P(A) = 0.2
P(B) = 0.2
The events are mutually exclusive.
So, as have
P(A or B) = P(A) + P(B)
If the events are independent, then
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = P(A) * P(B)
So, we have
P(A and B) = 0.2 + 0.2 - 0.2 - 0.2 = 0
P(A and B) = 0.2 * 0.2 = 0.04
The above equations are not equal
Hence, the events are not independent
