Answer:


(1)/(32)

Explanation:

According to Reese's model, let the head of the coin represent male, and the tail represents female. The outcome can either be a male or a female.

Total outcome = 2

pr(male) =
(1)/(2)

pr(female) =
(1)/(2)

Therefore the probability of male equals the probability of females i.e
(1)/(2).

Therefore,

pr(a litter of 5 puppies will be males) =
(1)/(2) x
(1)/(2) x
(1)/(2) x
(1)/(2) x
(1)/(2)

=
(1)/(32)

According to Reese's model, the probability that a litter of 5 puppies will be males is
(1)/(32).
