Answers

Answer:

Choice D

Step-by-step explanation:

probability of B given A

given you win the first race, you win the second race

Answer: The correct option is

(D) The probability that you win the second race given that you win the first race.

Step-by-step explanation: We are given the following two events :

A : You win the first race

B : You win the second race.

We are given to select the statement that represents P(B\A).

We know that

for any two events R and Q, the probability P(Q\R) represents the probability of happening of event Q given that the event R has already happened.

Therefore, for the given two events A and B,

the probability P(B\A) represents the probability that you win the second race given that you win the first race.

Thus, (D) is the correct option.

80% of a number is 96. What is 25% of that same number?

A.
20

B.
30

C.
40

D.
120

Answers

$(80)/(100)*x=96$ ⇒ $(80/20)/(100/20) *x=96$

$(4)/(5)*x=96$ ⇒ $x= (96*5)/(4)=24*5$

$\boxed {x=120}$

$(25)/(100)*x= (25/25)/(100/25)*120 = (120)/(4) = \boxed {30}$

The answer is B.

let the number be x
80%*x=96
x=96/80%
x=120
then 25% of 120 is your answer to find this half 120 twice
half 120=60
half 60=30

Therefore 30 is the answer which is B
