b = -33/l

Step-by-step explanation:

-1lb + 7 = 40

-1lb = 33 (subtraction property of equality)

-1lb/l = 33/l (division property of equality)

-1b/-1 = -33/l (division property of equality)

b = -33/l (solved)

The probability that 4 adults selected at random from the town all have health insurance is 0.1897

Step-by-step explanation:

Consider the provided information.

It is given that 66% of adults have health insurance.

Let p = 66% = 0.66

Therefore q=1-0.66=0.34

We need to find the probability that 4 adults selected at random from the town all have health insurance.

$P(x)=^nC_r(p)^r(q)^{n-r}$

Here the value of r is 4.

Substitute the respective values in the above formula.

$P(x)=^4C_4(0.66)^4(0.34)^{4-4}$

$P(x)=(0.66)^4(0.34)^{0}\\P(x)=0.1897$

Hence, the probability that 4 adults selected at random from the town all have health insurance is 0.1897
