The complete question is;
Five people buy individual insurance policies. According to the research, the probability of each of these people not filing a claim for at least 5 years is 2/3.
The probability that all 5 have not filed a claim after 5 years is A: 0.132 B: 0.868 C: 1 , and the probability that exactly 3 will have filed a claim after 5 years is A: 0.016 B: 0.033 C: 0.067
Answer:
1) P(all 5 file no claim after 5 years) = 0.132
2) P(exactly 3 file claim after 5 years) = 0.033
Step-by-step explanation:
1) we are told that the probability of each of these people not filing a claim for at least 5 years is 2/3.
Thus, for all 5 of them,
The probability will be;
P(all 5 file no claim after 5 years) = (2/3)^5 = 0.1317 ≈ 0.132
2) since probability of each not filing a claim for last 5 years = 2/3
Then probability of each filing a claim after 5 years = 1 - 2/3 = 1/3
So, P(exactly 3 file claim after 5 years) = (1/3)^3 ≈ 0.037.
The closest answer is 0.033.
umm I don't know hehe oops
Step-by-step explanation:
Step 1: Write our Givens

Move the constant term ,(the term with no variable) to the right side.
Here we have a negative 7, so we add 7 to both sides

Next, we take the linear coeffeicent and divide it by 2 then square it.

Then we add that to both sides


Next, we factor the left,

we got 5 because 5 add to 10 and multiply to 25 as well.
so we get

This is called a perfect square trinomial.
Next, we take the square root of both sides

± menas that we have a positive and negative solution.
Subtract 5 form both side so we get

The greater solution is when sqr root of 32 is positive so the answer to that is
