Event B is dependent on event A, and event A occurs before event B. Which formula can be used to find the probability of event A?a. P(A and B)
P(B)

b. P(A and B)
P(B|A)

c. P(A and B)
P(A|B)

d. P(A and B) × P(B|A)
e. P(A and B) × P(B)

Answers

Answer:

Option d - P(A)=\text{P(A and B)} * P(B|A)

Step-by-step explanation:

Given : Event B is dependent on event A, and event A occurs before event B.

To find : Which formula can be used to find the probability of event A?

Solution :

Event B is dependent on event A

i.e. The intersection of A and B - A and B

Probability of event B is dependent on event A is P(A and B)

Event A occurs before event B

i.e. B|A

Probability of event A occurs before event B is P(B|A)

Event B is dependent on event A, and event A occurs before event B is

\text{P(A and B)} * P(B|A)

The formula which shows the probability of event A is

P(A)=\text{P(A and B)} * P(B|A)

Therefore, Option d is correct.  
The right answer for the question that is being asked and shown above is that: "d. P(A and B) × P(B|A)." Event B is dependent on event A, and event A occurs before event B. the formula that can be used to find the probability of event A is P(A and B) × P(B|A)

Adam runs 4 miles in 20 minutes. How many miles does he run in 1 hour?

​

Answers

Answer: Adam will run 12 miles in 1 hour.

Step-by-step explanation:

Ok, so we know 4 miles in 20 minutes, correct?

Multiply 20x2. You will get 40. Then, multiply 4x2. That is 8. So in 40 minutes he ran 8 miles. So if we multiply 20x3, we would get 60 minutes which is an hour. So we need to multiply 4 by 3–12.

Answer: 12 miles

Step-by-step explanation:

Selma's class is making care packages to give to victims of a natural disaster. Selma packs one box in 5 minutes and has already packed 12 boxes. Her friend Trudy packs one box in 7 minutes and has already packed 18 boxes. How many more minutes does each need to work in order to have backed the same number of boxes?

Answers

Every 35 minutes Selma packs 7 boxes, while Trudy packs 5 boxes.

Thus every 35 minutes Selma decreases the difference between them in 2 boxes.

Since the original difference was 6 boxes, Selma needs 3 times 35 minutes, or 105 minutes, in all, to catch Trudy.

Answer- 105 minutes, or 1 hour and 45 minutes.

the area of a rectangular plot 30 feet long and 20 feet wide will be doubled by creating a border around the plot. what width should the border be to accomplish this?

Answers

Answer:

(2x + 20)(2x + 30) = 1200 Aplus

Step-by-step explanation:
the area of the plot is 600 (20x30) and it needs to be 1200 (600x2)
only the width is changed so you divide it by the length which is 30 
1200 divided 30 is 40 so the answer is 40 (another way is to just multiply the width by 2 since it's the only thing changing)
