Q and R are not mutually exclusive events. If P (Q) = 5/8 and P (R) = 1/8 and P (Q and R) = 1/32, Find P (q or R)

The solution for this problem is just adding and subtracting fractions. We all know how to add and subtract function because our teacher since high school teach us how to. P (Q or R) = P (Q) + P (R) - P (Q and R) = 5/8 + 1/8 - 1/32 = 23/32

The answer to this question is 23/32.

Given that the events are not mutually exclusive the union of the probability of the events is calculated through the equation,

P (Q or R) = P (Q) + P (R) - P (Q and R)

Substituting the known values,

P (Q or R) = 5/8 + 1/8 - 1/32

Simplifying,

P (Q or R) = 23/32

The answer to this item is 23/32.
