Given the following information about events A, B and C determine which pairs of events, if any, are independent and which are m

kow [346]

Answer:

a. Are B and C independent? NO

b. Are A and C mutually exclusive? NO

c. Are A and B independent? YES

d. Are A and B mutually exclusive? NO

Step-by-step explanation:

Given the data in the question;

P(A|B) = 0.26 P(A) [ A and B are independent ]

P(B|C) = 0 [ B and C are mutually exclusive ]

P(C/A) = 0.26 ≠ P(C)

hence, [A and C are neither independent nor mutually Exclusive]

Therefore;

a. Are B and C independent? NO

b. Are A and C mutually exclusive? NO

c. Are A and B independent? YES

d. Are A and B mutually exclusive? NO

For a scavenger hunt, Jim's mom distributed a bag of 875 jelly beans evenly into 25 plastic containers and hid them around the

kupik [55]

Answer:

Jim only found 15 of the containers.

Step-by-step explanation:

If his mom hid 875 jelly beans evenly into 25 containers we can easily multiply 25 x 35 = 875, which means there were 35 jelly beans in each container.

Jim only found an amount of 385 jelly beans. To find out how many containers he found, all you have to do is divide 385 by 25 which gives us 15.4.

15.4 rounded to the nearest whole number is 15. So your answer would be that Jim found only 15 out of 25 containers.

A group consists of 10 men and 11 women. in how many ways can a team of exactly 4 men and 6 women be selected?

maks197457 [2]

C(10,4)×C(11,6) = 210×462 = 97,020

_____
Any of the choices of 4 of 10 men can be combined with any of the choices of 6 of 11 women. The "n choose k" function, C(n, k) is computed as n!/(k!×(n-k)!).

What is the area of LMN

irakobra [83]

4 square units.

The easiest way to find this is by looking at the triangle as if NL was the base. In this case PM would be the height. Since a triangle is the same shape even when we move it or rotate it, this is a common strategy to finding areas when the direction is tough for us.

Now that we have this we can measure the lengths of the base and height and use them in the triangle area formula.

Base = 4

Height = 2

Area of a triangle = 1/2bh

Area of a triangle = 1/2(4)(2)

Area of a triangle = 2(2)

Area of a triangle = 4
