The probability of getting a 2 or a getting a black card, find individual probabilities;
A standard deck has 52 cards.
There are 4 2's in a normal deck; probability of getting it is 4/25
The probability of getting a black card is; 26/52 since half the deck is red and black.
Now add up the probabilities since it says "or"
(4/52)+(26/52)=30/52 probability of the card that you were dealt being a two or a black card.
Hope I helped :)
Answer: (x+8)^2 = 127
Step-by-step explanation:
A = L * W = 75 so L = 75/W Cost = 4W + 8(2L + W) = 4W + 16L + 8W = 12W + 16L = 12W + 1200/W C' = (12(W^2 - 100))/(W^2) = (12(W-10)(W+10))/(W^2) so W = 10 then L = 7.5
Answer:
A
Step-by-step explanation:
You can add the numbers to get the perimeter
10 1/3 + 15 2/3 = 26
18 1/4 + 24 1/4= 42 1/2
26 + 42 1/2= 68 1/2
That is answer choice A
