really all you have to do is multiply 126 * 2 * 7 * 3
then all that's next is to just put the letters in the order they were originally at the end of the answer
Answer: P(A and B) is greater than P(A)
P(A and B) should be smaller than P(A).
Step-by-step explanation:
Given : P(A and B) = 0.40
P(A) = 0.20
Using the given formula of the conditional probability will be
But we know that the probability of any event cannot be more than 1.
Also, the probability of the intersection must be less than the probability of individual event.
Thus , in the given question P(A and B) must be smaller than P(A).
We are given statement " gained 20 pounds and loses 15 pounds".
<em>Note: We take plus or positive sign for gain word and we take minus or negative sign for the loses word.</em>
Gained 20 means +20.
Loses 15 mean -15.
Therefore, we can setup an expression as:
<h3>+20 -15.</h3>
20 is a positive number and 15 is a negative number.
Because we have opposite signs of numbers, we would subtract them.
20-15 = 5 pounds.
It’s the first one.
