A car insurance company has determined that 66% of all drivers were involved in a car accident last year. Among the 1010 driver

jenyasd209 [6]

Answer: Our required probability is 0.618.

Step-by-step explanation:

Since we have given that

Probability of all drivers were involved in a car accident last year = 66%

Number of drivers = 10

Number of drivers involved in a car accident = 3

So, probability of drivers involved in car accident is given by

$\dfrac{3}{10}\\\\=0.3$

Probability of getting 3 or more who were involved in a car accident is given by

P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)

Here,

$P(X=0)=^{10}C_0(0.7)^{10}=0.028\\\\P(X=1)=^{10}C_1(0.7)^9(0.3)=0.121\\\\P(X=2)=^{10}C_2(0.7)^8(0.3)^2=0.233$

So, our equation becomes

P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)

$P(X\geq 3)=1-0.028-0.121-0.233=0.618$

Hence, our required probability is 0.618.

The diameters of a circle is 7m. Find its area to the nearest tenth?? Help please

Lady bird [3.3K]

Area = $\pi r^{2}$

The diameter is double the length of the radius

7 ÷ 2 = 3.5

3.5 × 3.5 = 12.25

$12.25\pi$ = 38.4845100064751

38.4845100064751 rounded to the nearest tenth is 38.5
