Question

He probability that a student is taking english is 4/5. the probability that a student is taking art is 2/9. the probability that a student is taking english or art is 8/9. what is the probability that a students is taking english and art

Answer 1

Probability that student is taking English, P(E)=4/5
Probability that student is taking art, P(A)=2/9
Thus:
The probability that a student is taking English and Art will be:
P(A) and P(E)
=P(A∩E)
=P(A)×P(E)
=4/5×2/9
=8/45
