Answer:
The probability is 1/51
Step-by-step explanation:
In a deck of cards, there are 52 cards
one king of spades and one king of club
If the first is a king of club, after drawing it, the number of cards that we will have left will be 52-1 = 51 cards
So the probability that the second is a king of spades is the number of king of spades/number of remaining cards
Mathematically that will be 1/51
(u - 3) • (u - 7) I believe
Put it in an equation;
it is given that 36 is the price after the 40% discount, so;
36=X*40%
X here is the original price
36=X*(40/100)
40X=3600
X=90$
Hope this helps.
