Answer:

The formula for the number of elements in the sample space (n(S)) can be calculated using the formula:

n(S) = n(A) / P(A)

where n(A) is the number of elements in the event A, and P(A) is the probability of event A.

Given that n(A) = 2 and P(A) = 15, substituting these values we get:

n(S) = 2 / 15

So, the number of elements in the sample space n(S) is approximately equal to 0.13.

Step-by-step explanation:

n(A) = 2

P(A) = 15

P(A) = n(A)/n(S)

15=2/n(s)

15×n(s) = 2

n(s) = 2/15

therefore, n(s) = 1/7.5
