(9c^2 + 3c + 9) - (9c^2 + 2c + 7)

Answers

Answer:

c+2

Step-by-step explanation:

Distribute the Negative Sign:

=9c2+3c+9+−1(9c2+2c+7)

=9c2+3c+9+−1(9c2)+−1(2c)+(−1)(7)

=9c2+3c+9+−9c2+−2c+−7

Combine Like Terms:

=9c2+3c+9+−9c2+−2c+−7

=(9c2+−9c2)+(3c+−2c)+(9+−7)

Answer:

c + 2

Step-by-step explanation:

(9c² + 3c + 9) - (9c² + 2c + 7)

9c² + 3c + 9 - 9c² - 2c - 7

c + 2

Suppose that two cards are randomly selected from a standard 52-card deck. (a) What is the probability that the first card is a clubclub and the second card is a clubclub if the sampling is done without replacement? (b) What is the probability that the first card is a clubclub and the second card is a clubclub if the sampling is done with replacement?

Answers

Answer:

(a) $(1)/(17)$ (b) $(1)/(16)$

Step-by-step explanation:

GIVEN: Suppose that two cards are randomly selected from a standard $52$ card deck.

TO FIND: (a) What is the probability that the first card is a club and the second card is a club if the sampling is done without replacement? (b) What is the probability that the first card is a club and the second card is a club if the sampling is done with replacement.

SOLUTION:

(a)

Probability that first card is club $P(A)=\frac{\text{total club cards}}{\text{total cards}}$
