In one town, 66% of adults have health insurance. What is the probability that 4 adults selected at random from the town all ha

LiRa [457]

Answer:

Probability that randomly selected 4 persons all have insurance is = 0.1897

Step-by-step explanation:

Given that the probability of having an insurance equals 66%=0.66

Thus

Probability that person A has insurance = 0.66

Probability that person B has insurance = 0.66

Probability that person C has insurance = 0.66

Probability that person D has insurance = 0.66

Probability that randomly selected 4 persons all have insurance is

$P(A)\times P(B)\times P(C)\times P(D)\\\\=0.66\times 0.66\times 0.66\times 0.66=0.1897$

16% of students play basketball. 70% of students live in Murfreesboro. 11% of students play basketball and live in Murfreesboro.

ycow [4]

Answer:

They are independent

Step-by-step explanation:

We have the following events:

* 16% of students play basketball

* 70% of students live in Murfreesboro

They ask us if each of the events are independent of the other, the answer is yes. Since the probability in the first event would be 16/100 and the second event 70/100, and at no time are they affected by each other.

They mention another event that that depends on these two:

* 11% of students play basketball and live in Murfreesboro

(16/100) * (70/100) = 0.112, which is equal to 11.2%, which is approximate to the event they mention.
