Mind exercise 7

In a family were born 7 children (no twins).

Following, three questions to keep the mind active and …. if you will be able to provide the correct answers, I could gadget you (at my discretion) an ebook I wrote.

1) What is the probability that the children could all be born in a day of the week? (no matter what) – very easy.

2) What is the probability that the children could all be born on a specific day of the week? – middle easy.

3) What is the probability that each of the 7 children have been born on a different day of the week? (one child per each day of the week) – few difficulty.

Waiting your reply ….
