Suppose two events A and B are mutually exclusive, with P(A) ≠ 0 and P(B) ≠ 0. By working through the following steps, you'll se
DanielleElmas [232]

Answer with Step-by-step explanation:

We are given that two events A and B are mutually exclusive.

A\cap B=\phi

P(A\cap B)=0

P(A)\neq 0

P(B)\neq 0

a.For mutually exclusive events,

P(A/B)=\frac{P(A\cap B)}{P(B)}=\frac{0}{P(A)}=0

Therefore, event A can not occurred if event B has occurred because two events can not occur together.

Answer:No, by definition mutually exclusive events cannot occur together.

b.When two events are independent

Then , P(A\cap B)=P(A)\cdot P(B)

P(A/B)=\frac{P(A)\cdot P(B)}{P(B)}=P(A)

If two events are mutually exclusive then

P(A\cap B)=0

Then , P(A/B)=0

Therefore, P(A/B)\neq P(A)

Hence, we can concluded that events A and B are not independent if they are mutually exclusive.

Answer:Yes, P(A/B)\neq P(A)

let's solve for x ~

  • 37x =  9x + 4

  • 37x - 9x = 4

  • 28x = 4

  • x =  \dfrac{4}{28}

  • x =  \dfrac{1}{7}

What is 2/3 + 3/4 I don’t understand it at all
victus00 [196]

Answer:

6/12 or half

this would be the answer because the lowest common denominator of 4 and 3 is 12 so you'd multiply them you'd get 12 then multiply 2 and 3 and get six therfore the answer is 6/12 or 1/2
