There are 12 face cards in a deck, and one you draw the first face card there will be 11 left so:
(12/52)*(11/51)=132/2652=11/221
The probability of hitting it once is the ratio of the bullseye area to the whole target.
So 144/484=.2975
For it to happen twice in a row, would be this squared which is .088=.09 or 9%
They are right triangles so you can use the Pythagorean theorem.
A = sqrt(5^2+3^2)
A = sqrt(25+9)
A = sqrt(34) (exact answer)
As a decimal it would be: 5.8
B = 45 = sqrt( 20^2 + b^2)
B^2 = 45^2-20^2
B^2 = 2025-400
B^2 = 1625
B = sqrt(1625)
B = 5sqrt(65) exact answer
As a decimal : 40.3
18
calculate
× 48 = 5 × 6 = 30
she had 30 foul shots hence 48 - 30 = 18
She made 18 shots
