The probability of an event
Readme [11.4K]

Answer:

d. is the sum of the probabilities of the sample points in the event.

Step-by-step explanation:

Suppose we have a fair coin then the the sample space S is given by {(H), (T)}

the head and tail are the sample points.

the probability of sample space will be given by the sum of probability of head and tail. P(S)= P(A) + P(B)

       1= 1/2+ 1/2

The total probability of the sample space always equals 1

The individual probabilities add up to to give the probability of the sample space.
