Question

An Australian Shepherd breeder has had three litters of puppies from the same set of parents. The following table shows the results from the three litters. In the next litter, what is the probability of a puppy having no spots? Enter a fraction or round your answer to 4 decimal places, if necessary. Number of Puppies Black and White Red and white Black with Spots Red with Spots 8 6 9 4

Answer 1

The total number of puppies can be gotten to be:

`\Rightarrow8+6+9+4=27`

The number of puppies without spots will be:

`\Rightarrow8+6=14`

Recall the probability definition and formula: A probability is the number of desired outcomes (D) divided by the number of total outcomes (T), that is:

`P=(D)/(T)`

From what we have calculated earlier, we have that:

`\begin{gathered} D=14 \\ T=27 \end{gathered}`

Therefore, the probability will be:

`P=(14)/(27)=0.5185`

The probability is 14/27 or 0.5185.
