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

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.
