Question

If n(A) = 2, P(A) = 0.5, then find n(S).​

Answer 1

Answer:

Solution :

Given n(A) = 2 , P(A) = 1/5,

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

= 2/(1/5)

= 2 × 5

= 10

Therefore ,

n(S) = 10

Option (A) is correct.

Answer 2

Explanation :-

= n(A) = 2

= P(A) = n(A) / n(S) = 0.5

*[ 0.5 can be written as 5 / 10 ]

= 2/n(S) = 5 / 10

= 2/n(S) = 1 / 2

= n(S) = 1
