By definition of conditional probability,
P(B | A) = P(A ∩ B)/P(A) = (13/25) / (13/20) = 20/25 = 4/5
Hey, can you please fix this question? I can't seem to understand it. When you do, please tell me so I can help you out!
The answer is 4,000 ft squared because since the sides are 100 ft and 80ft then we need to multiply them which is 8,000 then divide that by 2 since it’s a triangle which is 4,000 ft squared.
The minimum number of T-shirt that they must sell to raise $500 is 67 T-shirts
Let x represent the number of Pi Day T-shirts sold.
They are selling Pi Day T-shirts for $7.50 each, So to raise $500:
7.5x > 500
Dividing through by 7.5:
7.5x / 7.5 > 500 / 7.5
x > 66.7
Hence, the minimum number of T-shirt that they must sell to raise $500 is 67 T-shirts

75-31= 44
44/75= 0.58666 or 58.7%
Subtract 31 from 75 since we're figuring out greater than or "equal to" we want to include the number 32 in our equation. If it was only "greater than" 32 then we'd subtract 32 from 75. Then you divide that number(44) by 75, which is all the possible outcomes you could have in this scenario. Move the decimal two places to the right to make it a percentage and you've got your answer.
