Suppose that the chances of any baby being male or female are even. A newly married couple plan to have three children.

  1. Denoting a male baby by M and a female baby by F, write down the sample space for the possible sex of all three children collectively. For example, MFM would denote the first and third babies were males and the second baby was female.
  2. What is the probability that only one child will be male?
  3. What is the probability that at least one child will be male?
