Suppose S and T are mutually exclusive events. Find P(S or T) if P(S) = 20% and P(T) = 22%.
Solution:
S and T are mutually exclusive events.
P(S) = 20% = 0.20
P(T) = 22% = 0.22
We know that
Probability of mutually exclusive events is
P(S or T) = P(S) + P(T)
Substituting the values
P(S or T) = 0.20 + 0.22
P(S or T) = 0.42
Therefore, the probability of (S or T) is 0.42
Suppose S and T are mutually exclusive events. Find P(S or T) if P(S) = 20% and P(T) = 22%.
Summary:
Suppose S and T are mutually exclusive events. If P(S) = 20% and P(T) = 22% P (S or T) = 0.42
