Answer 1

${\huge {\mathfrak {\orange {Answer :-}}}}$

A.

Number of marbles with 'B' written on them is [ n(A)] = 6.

Total number of marbles [ n(S)] = 15.

Thus, Probability is

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

= 6/15 = 2/5. ⬅️

B.

Number of green marbles [ n(A)] = 5.

Total number of marbles [ n(S)] = 15.

Thus, Probability is

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

= 5/15 = 1/3 ⬅️
