A: When a baby is born, it is a girl.
B: When a 7-sided die is rolled, the outcome is 4.
Find P(A and B), the probability that events A and B both occur.
A: a baby can be girl or boy the probability getting one of them is \(\frac12\)
B: on the 7 sided die 7 numbers so the probability getting 4 is \(\frac17\)
Answer:\(\frac12\times\frac17=\frac1{14}\)
