According to scientific research, the probability that a person between the ages of 20 and 25 having high blood pressure, is only 17 %. In a random survey of 10 people in this age group, what is the probability that two or fewer have high blood pressure?

The probability of having high blood pressure is 17%.

We need to find the probability of 2 or fewer have high blood pressure.

Possibility 1: No one have high blood pressure.

The probability is .

Possibility 2: Only one have high blood pressure.

The probability is .

Possibility 3: 2 among the 10 have the high blood pressure.

.
