Find the probability p(e or f) if e and f are mutually exclusive, p(e)=0.30, and p(f)=0.45.
the probability of p(e or f) is

Probabilities are used to determine the chances of an event.

The probability of P(E or F) is 0.75

The parameters are given as:

So, the equation becomes

Hence,  the probability of P(E or F) is 0.75

P(E or F) = 0.75

Step-by-step explanation:

Given;

P(E)=0.30

P(F)=0.45

We need to find probability of P(E or F).

Now by General theorem of probability addition theorem:

P(E or F) = P(E) + P(F) - P(E and F)

For mutually exclusive events, P(E and F) = 0

So, P(E or F) = P(E) + P(F) =

Hence P(E or F) = 0.75
