    Easy, easy question--please help...

    I have not taken stats in a long time and I was having trouble trying to solve this problem...

    "When a woman is injected with an egg fertilized in vitro, the probability of it implanting successfully is 20%. If a woman is injected with five eggs simultaneously, what is the probability that she will become pregnant?"

    thanks for the help.

    The way to deal with this is to reverse it.

    With each egg, there is an 80% prob that it won't take. What is the total prob. that she will NOT get pregnant? 100 - that.
