Question

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

Answer 1

I think that it's 1/32 if i'm not right pleas tell me.

Explanation:

Answer 2

`(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)`.
