73 + 55 = 52 + n
Subtract 52 from each side:
73 + 3 = n
n = 76
(2,5)(-1,5)....notice that ur y's are the same number...they are both 5.
This means that u have a horizontal line which has a slope of 0. If the y's are the exact same number, then u have a horizontal line.
if the x's would have been the same number, then u would have had a vertical line with an undefined slope
Answer:
0.5
Step-by-step explanation:
Answer:
The required probability is, 0.78
Step-by-step explanation:
There are, (52 - 13) = 39 cards which are not spade
5 cards can be chosen from the deck of 52 cards in
ways
and out of these 5 choices, none of them will be spade in,
ways
So,
P(None of the chosen cards is spade)
= 

Hence,
P(out of these 5 choices, at least one card is spade)

= 0.78
