Marcos is doing a card trick using a standard 52-card deck with four suits: hearts, diamonds, spades, and clubs. he shows his friend a card, replaces it, and then shows his friend another card. what is the probability that the first card is a club and the second card is not a heart?
a. 3/16
b. 1/2
c. 1/8
d. 5/8

Option A is correct.

Step-by-step explanation:

Probability of getting a club =

Probability of getting a heart = Probability of getting a club =

So, Probability of not getting a heart =

⇒ Probability of getting first card a club and second not heart =

                                                                                                        =

Therefore, Option A is correct.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
