The answer is 1/2
Since we know that one is already is a girl
Second child can be a girl or a boy
Hence, the probability of being a girl = 1/2

A family has four children, of age 3, 6, and 16 and 16 . Let’s assume that the probability of giving birth to a boy is the same as the probability of giving birth to a girl. Determine the following probabilities: (a) that all 4 children are girls (b) that at least two of the children are boys (c) that the oldest child is a girl (d) that only three children are of the same gender (e) Given that you...

A family has three children. Every child was born to be a boy or girl with 50% chance. The probability of this family having at least one boy is?
2. Suppose that a family is going to keep having children until they have at least one girl. Further suppose we can model successive births as boy and one independent trials with p P(girl) and P(boy) = 1 - p. Let Y denote the total number of children in the family. Compute, for y 2, (i) the probability that the first boy born is the y-th child born; [2] (ii the probability that the first girl born is the y-th...
