Q.16 If n(S) = 40 and P(A) = 3/8, find n(A).

Answer: n(A) = 15 P(A) = n(A)/n(S) ⇒ 3/8 = n(A)/40 ⇒ n(A) = (3 × 40)/8 = 15

If \(n(S) = 40\) and \(P(A) = \dfrac{3}{8}\), find \(n(A)\).

Best answer

Answer: n(A) = 15

\(P(A) = \dfrac{n(A)}{n(S)} \Rightarrow \dfrac{3}{8} = \dfrac{n(A)}{40} \Rightarrow n(A) = \dfrac{3 \times 40}{8} = 15\)
