    Question Hi I need some help with a probability problem.

    I need to know the answer and if possible the process for finding the answer to the following problem:

    What is the probability that a ten child family will include 5 boys ina row?

    I really would like to know what the possible number of favourable events there are and if someone can take the time - the actual combinations in a 10 child family.

    Thanks for the help.

    Re: Hi I need some help with a probability problem.

    Does not matter how many kids a family has.
    Prob(1st=boy)=.51
    Prob(2nd=boy)=.51
    Prob(3rd=boy)=.51
    Prob(4th=boy)=.51
    Prob(5th=boy)=.51

    Prob(1&2&3&4&5=boy)=0.51^5=.034503
