Answer:
option B is correct, i.e. 1/12.
Step-by-step explanation:
You roll a number cube twice.
the probability of rolling a "2" first is P(A) = 1/6.
And then rolling an "odd number" is P(B) = 3/6.
Since two events are independent of each other, we can use following rule:-
P(A and B) = P(A)*P(B)
Combined probability of two events is:-
P(A and B) = (1/6)*(3/6) = 3/36 = 1/12.
Hence, option B is correct, i.e. 1/12.
