Hi all,

Just checking my answer in the following problem. Suppose 100 women with a probabilty P of getting pregnant = 0.1 in an "attempt". How many women are pregnant after the 3rd attempt.

My solution is:
after attempt 1: 10% = 10 women
after attempt 2 in 100-10 = 90 women: 10% = 9 women
after attempt 3 in 90-9 = 81 women: 10% = 8 women.
after 100 women around 27 women are pregnant after 3 attempts have been "made".
Correct?

regards,

Marc
