Answer:
of(x) = (x-7)(x-5)(x - 5)(x + 2)
Step-by-step explanation:
There are 13 heart cards
Now 1 heart card can be drawn from a pack of 13 heart cards in 13C1 ways
13C1=13
Also,1 card can be drawn from a pack of 52 cards in 52C1 ways
52C1=52
The probability of drawing a heart card from a pack of 52 cards is
13/52=1/4
there are 26 black cards in total
(13 spades +13 clubs)
Now 1 black card can be drawn from a pack of 26 black cards in 26C1 ways
26C1=26
Also,1 card can be drawn from a pack of 52 cards in 52C1 ways
52C1=52
The probability of drawing a black card from a pack of 52 cards is
26/52=1/2
Now as both the task are performed one after the other and after replacement so the probability of drawing a heart after a black card is
=1/2 * 1/4
=1/8
Prime means when a number can't have a factor other than 1
Its .03311258 if you wanna round its about .33
