Question

If n (s) = 36, P (A) =5/12 find n(A)​

Answer 1

Answer:

n(S) : 36

A:5/12

n(A) :36×5/12

36×3

108

Answer 2

Answer:

The correct answer is 15.

Step-by-step explanation:

Given:

Total outcomes =  n(S) = 36(total number of sample cases)

Probability of A chances = 5/12

Formula used: P(E) = Favorable outcomes / Total outcomes

The answer has to be the number of favorable outcomes = n(A)

Putting the given values in above formula :

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

⇒ n(A)= P(A)* n(S)

⇒ n(A)= (5/12) * 36

⇒ n(A)= 5*3

⇒ n(A) =15

The total number of possible events that could take place is termed as total outcomes in probability .

Favorable outcomes in probability means the number of events that are being considered.

The number of ways of achieving success for a particular case being considered is termed as probability .
