Given a sample space, and events A and B, where P(A)= 0.5 and P(B)=0.5. Which of the following values for P(A and B) are not pos
user100 [1]

Option a, option b, option c, option d are not possible values for P(A ∩ B)

Solution:

Given A and B are independent events.

P(A) = 0.5 and P(B) = 0.5

To find which of the following values for P(A and B) are not possible.

P(A and B) = P(A ∩ B)

P(A ∩ B) = P(A) × P(B)

              = 0.5 × 0.5

P(A ∩ B) = 0.25

Option a: All are possible.

All answers are not possible for two independent events.

Option b: 0.35

We found that P(A and B) is 0.25.

So, 0.35 is not possible value.

Option c: 0.5

We found that P(A and B) is 0.25.

So, 0.5 is not possible value.

Option d: 0

We found that P(A and B) is 0.25.

So, 0 is not possible value.

Option e: 0.25

We found that P(A and B) is 0.25.

So, 0.25 is the possible value.

Hence, 0.35, 0.5, 0 are not possible values.

What is the probability of randomly picking a girl without brown hair
ikadub [295]
6 girls have brown hair, and you want to know the probability of finding one without brown hair, so you take the population and subtract brown hair, or 22. You have a 22/28 chance of picking a girl without brown hair, simplified to 11/14.

A researcher testing seed varieties for tulips got a confidence interval of (14.2%,17.4%) for the percent of seeds that can grow
Alex73 [517]

Answer:

The sample proportion is 0.158.

Step-by-step explanation:

In a confidence interval of proportions, we have the lower bound and the upper bound of the interval. The sample proportion is the halfway points between these bounds, that is, the sum of these bounds divided by 2.

In this problem, we have that:

Lower bound: 0.142

Upper bound: 0.174

Sample proportion: (0.142+0.174)/2 = 0.158

The sample proportion is 0.158.
