Find the probability P(E or F) if E and F are mutually exclusive and P(E)=0.30 and P(F) =0.47
0.77
To find the probability P(E or F) when E and F are mutually exclusive, we can use the formula:
P(E or F) = P(E) + P(F)
Since E and F are mutually exclusive, it means that they cannot occur at the same time. Therefore, the probability of both E and F happening together is 0.
Given that P(E) = 0.30 and P(F) = 0.47, we can substitute these values into our formula:
P(E or F) = P(E) + P(F)
= 0.30 + 0.47
= 0.77
So, the probability P(E or F) is 0.77.
