Question

Mrs. Grundy has two children. Given that Mrs. Grundy has at least one child born on a Monday, what is the probability that both her children were born on Mondays?

Answer 1

Answer: Ok, the chanche of both children were born on a monday is $\frac{1}{7}$

Step-by-step explanation: Well, we alredy know that one of her children was born on a monday, when they ask the probability of both children were born on a monday, we only need to see the case of the second kid.

So, the week has 7 days, ence the probability for each day (in this case a monday) is 1/7.
