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?



a)1/2

b)1/10

c)1/16

d)1/32

Answer 1

Hi Skye,

 

Using a coin the we can say heads would be  female and tails would be male.

 

P(tails on first toss) = 1/2

P(tails on 2nd toss) = 1/2

P(tails on 3rd toss) = 1/2

etc

 

So the probability of tails on all 5 tosses is (1/2)⁵ = 1/32 D
