Question

If Westville has 15,200 households, predict the number of households that will have exactly 3 computers? Please answer I need help

Answer 1

Answer:

1140 households

Step-by-step explanation:

The results of a computer survey of 80 households in Westville are shown in the table.

So from the table we can see that 6 households have 3 numbers of computers.

So the probability is $\frac{6}{80}$

Therefore, the probability of number of houses from a total of 15,200 houses to have exactly three computers is = $\frac{6}{80} \times 15200$

                                                          = 1140 houses
