If a couple plans on having 4 children, what is the probability that there will at least have one boy? assume boys and girls are equally likely. is that probability high enough for the couple to be very confident that they will atleast get one boy?
---
P(at least one boy) = 1 - P(4 girls) = 1 - (1/2)^4 = 15/16
