According to scientific research, the probability that a person between the ages of 20 and 25 having high blood pressure, is onl
boyakko [2]

Answer:

<h2>The probability is {\frac{83}{100} }^9 \times \frac{17}{100} + {\frac{83}{100} }^8 \times {\frac{17}{100} }^2 + {\frac{83}{100} }^{10}.</h2>

Step-by-step explanation:

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 {\frac{100 -17}{100} }^{10} = {\frac{83}{100} }^{10}.

Possibility 2: Only one have high blood pressure.

The probability is {\frac{83}{100} }^9 \times \frac{17}{100}.

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

{\frac{83}{100} }^8 \times {\frac{17}{100} }^2.

Any of the possibilities can happen.

Hence, the required probability is {\frac{83}{100} }^9 \times \frac{17}{100} + {\frac{83}{100} }^8 \times {\frac{17}{100} }^2 + {\frac{83}{100} }^{10}.
