Reese is using a coin to predict the gender of the puppies born to her dog. According to Reese’s model, which is the probability that a litter of 5 puppies will be all males?

StartFraction 1 over 32 EndFraction
StartFraction 1 over 16 EndFraction
StartFraction 1 over 10 EndFraction
One-half

The probability that a litter of 5 puppies will all be males according to Reese's model is StartFraction 1 over 32 EndFraction.

This is because the probability of flipping a coin and getting heads (representing a male puppy in Reese's model) is 1/2. The probability of flipping heads 5 times in a row is (1/2)^5 = 1/32.
