Answer 1

Answer:

Step-by-step explanatifhon:

Answer 2

Answer:

Given:

Probability of student studying maths : P(A)= 60/100

Probability of student studying maths and science : P(A∩B)= 40/100

Probability of student studying science : P(B)

Step-by-step explanation:

Probability of student studying science if he is already studying maths:

P(B/A)= (P(B)* P(A/B))/P(A)  = P(A∩B) / P(A) = 0.4/0.6 =2/3
