Answer:
The value of P(S or T) is 3/4.
Step-by-step explanation:
It is given that S and T are mutually exclusive events. It means intersection of S and T is 0.
We need to find the value of P(S or T). It means we have to find the probability of union of S and T.
Substitute the given values in the above formula.
Therefore the value of P(S or T) is 3/4.
Answer:
P(S or T)= 3/4
Step-by-step explanation:
Given:
S and T are mutually exclusive events
find P(S or T)
P(S or T)= P(S) + P(T)
= 1/3 +5/12
=4+5/12
=9/12
=3/4 !
