one town, 64% of adults have health insurance. What is the probability that 10 adults selected at random from the town all have

Katena32 [7]

Answer:

The probability that 10 adults selected at random from the town all have health insurance is 0.01153.

Step-by-step explanation:

Consider the provided information.

One town, 64% of adults have health insurance.

Let p = 64% = 0.64

Therefore, q=1-0.64=0.36

We need to find the probability that 10 adults selected at random from the town all have health insurance

Use the formula: $P(x)=^nC_r(p)^r(q)^{n-r}$

Here, the value of r is 10.

Substitute the respective values in the above formula.

$P(x)=^{10}C_{10}(0.64)^{10}(0.36)^{10-10}$

$P(x)=(0.64)^{10}(0.36)^{0}\\P(x)=(0.64)^{10}\\P(x)\approx0.01153$

Hence, the probability that 10 adults selected at random from the town all have health insurance is 0.01153.

What is 63.5% written as a decimal? A. 0.0635 B. 0.635 C. 6.35 D. 635

jek_recluse [69]

Answer:

B. 0.635

Step-by-step explanation:

Having a percent means its out of 100 so we can turn the percent into a fraction. 63.5/100

We cant have a decimal in our fraction, so we can multiply by 10 to get rid of it. (63.5*10)/(100*10)=635/1000

Since the denominator is a multiply of 10, we can convert the numerator into a decimal. .635

So your answer would be B. 0.635
