Question

can someone plzz give me the answer? ​

Answer 1

let us total .no. of students ,n(S) =135+65=>200

1. The .no. of students who likes opinion, n (L) .(say)=135->A
2. The .no. of students who dislikes opinion , n(S) =65->B

for case 1) P (A)=n (A)÷n(S)

=>p (A)= 135÷200=0.68

for case 2) P (B)=n(B)=n(S)

=>P(B)=65÷200=0.32
