First, let's count:
there are 26 possible outcomes for E1 (black card)
there are 4x9 = 36 possible outcomes for E2, to pick a numbered card (any color)
there are 2x9 =18 possible outcomes for E1 (black) AND E2 (numbered, spade + clower)
the probability of E1 AND E2 is the ratio of the count of possible outcomes for E1 + E2 and the count of all possible outcomes (52 choices to pick a card from the deck):
P(E1 and E2) = 18/52 (34.6%)
And as asked:
P(E1) = 26/52 = 1/2 (50%)
P(E2) = 36/52 = 9/13 (69.2%)
Answer:x=-1 y=-10
Step-by-step explanation:
"2(x-3)=-8"="2x-6=-8"="2x-=-2"
x=-1
y+3=-2y-27
3y+3=-27
3y=-30
y=-10
90 + 2x + 1 + 5x + 5 = 180
7x + 96 = 180
7x = 84
X = 12
Answer: width would be 7 feet and the length would be 26
Step-by-step explanation:
width : w
length: 19 +w
2l + 2w = 66
2(19+w) + 2w= 66 distribute
38 + 2w + 2w = 66 add the w values
38 + 4w =66 subtract 38 from both sides
4w = 28 divide by 4
w= 7
19+7= 26
l=26
