Suppose you adopt the strategy to bear children until the first girl is born. Suppose that the probability of a boy on each birth is 0.5, and that each birth is independent and yields a single birth (no twins).
a. Find the mean/expected number of births on which the first girl is born.
b. Find the mean/expected number of boys born before the first girl is born.
c. Find the standard deviation of the number boys born before the first girl is born.
d. Find the probability that the number of boys born before the first girl is born is within one standard deviation of the mean.

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
