According to the Center for Paranormal Activity and Defense (a secret division of the FBI), 10% of people have come in contact with an extraterrestrial being. Suppose 10 people are randomly selected and the numbers who have come in contact with extraterrestrial beings is recorded. What is the probability that exactly two of the ten have come in contact with an extraterrestrial being

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer4 to the second power is 16

and 4 to the third power is 64,
