Question

if n(A)=¼,n(S)=¾ then find the P(A)​

Answer 1

Answer:

P(A) = 1/3

Step-by-step explanation:

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

n(A)/n(S) = (1/4)/(3/4)

coverting (1/4)/(3/4) to multiplicative number will interchange the denominator (3/4) their numerator and denoinator i.e 3/4 will become 4/3

i.e 1/4 * 4/3 = 1/3
