Answer:

option D

Yes, they are independent because P(A)×P(B)=P(A∩B)

Step-by-step explanation:

Given in the question,

p(A) = 3/5

p(B) = 4/7

p(A∩B) = 12/35

If two events A and B are independent then,

<h3>P(A n B)= P(A).P(B)</h3>

12/35 = 3/5 . 4/7

12/35 = 12/35

Hence, events A and B independent events

maxonik [38]

Answer: 11 months

Step-by-step explanation:

Let the number of months that it will take him to reach his goal be represented by x.

Based on the information given in the question, this can be formed into an equation as:

8 + 4x = 52

4x = 52 - 8

4x = 44

x = 44/4

x = 11

It will take 11 months to reach the goal

Step-by-step explanation:

Total amount of apples in one bag:

x + y + z

Hence, total amount of apples in two bags:

2(x + y + z)

or

2x + 2y + 2z

or

x + x + y + y + z +  z

Hence, B, D and E are correct.

A is incorrect because you are adding 2 more apples on top of the total amount of apples in one bag, and you cannot assume that there are 2 apples in each bag.

C is incorrect because you are multiplying the apples together, but you are supposed to add them up to find the total.

F is incorrect because you are finding 1/2 a bag.
