You have a standard deck of 52 cards. you pick one card and then, with out putting the first card back, you pick a second card. what is the probability that both cards will be 9s?

First, find the probability of picking one 9. There are four nines in a deck of 52, so the probability is 4/52, which is 1/13.

The probability of picking a 9 the second time is 1/17, because if a 9 was picked the first time, then there are three 9s left and 51 cards left in total.

To find the probability of both events happening, multiply the individual probabilities together:

(1/13)(1/17)

 The probability that both cards picked will be 9s is 1/221.

the answer to the question is a  

it has the same slope and the same y-intercept.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
