A couple plans to have children until they get a girl, but they agree that they will not have more than three children even if all are boys. (Assume boys and girls are equally likely.) a) they might have. b) Find the expected number of children. c) Find the expected number of boys they’ll have.

a. (0.5)^3*(0.5)^0*3C0 +0.5^2*0.5^1*3C1+0.5^1*0.5^2*3C2 +0.5^0*0.5^3*3C3

b. probability of having a girl 1/2 and that of boy is 1/2 but for the occurrence 0,1,2,3 it is 7/8 the number of children may be 2

c. 7/8, 7 out of 8 for the four possible occurrences.; 1

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
