SOLUTION:

From the given information, let X be the number of households own three or more dogs.

The probability that households own three or more dogs is p =12%= 0.12.

Number of households selected n =4.

Here, X Binomial ( n=4,p=0.12).

The probability mass function of X is,

Compute the probability that at least one household has three or more dogs.


.


Therefore, the probability that at least one household has three or more dogs is 0.4003.
