Since S and T are mutually exclusive events, their intersection is empty. Therefore, the probability of the union of S and T is equal to the sum of their probabilities:
P(S or T) = P(S) + P(T)
P(S or T) = 3/8 + 1/8
P(S or T) = 4/8
P(S or T) = 1/2
Therefore, the probability of S or T occurring is 1/2.
S and T are mutually exclusive events. Find P(S or T).P(S)equals three eighths, P(T)equals one eighth
