Jackson owes his sister Monica $15. Explain the meaning of zero in this situation.

ludmilkaskok [199]

accounting wise, if a value is positive, is an asset, you're above water, +50, you have 50 bucks in your account/pocket.

if a value is negative, is a liability, you're below water, -50, you owe 50 bucks, you're in the hole for 50 clams.

so Jackson owes Monica $15, he's in the hole for 15 bucks, namely his balance with his sister is -15.

if he pays her $1, he owes her 14, so -14 is his balance, let's make a quick table of that

pays her 1................... -14

pays her 2..................-13

pays her 3...................-12

and so on

pays her 13.................-2

pays her 15..................0

0 means, he paid her in full.

The probability that event A occurs is 0.4, and the probability that events A and B both occur is 0.25. If the probability that

ICE Princess25 [194]

Answer:

The probability that event B will occur is 0.45

Step-by-step explanation:

Given;

probability that event A occurs, P(A) = 0.4

the probability that events A and B both occur, P(A ∩ B) = 0.25

the probability that either event A or event B occurs, P(A ∪ B) = 0.6

To determine the probability that event B will occur, we use probability addition rule;

P(A) + P(B) = P(A ∩ B) + P(A ∪ B)

0.4 + P(B) = 0.25 + 0.6

0.4 + P(B) = 0.85

P(B) = 0.85 - 0.4

P(B) = 0.45

Therefore, the probability that event B will occur is 0.45
