Using an ordinary deck of 52 playing cards, you are dealt three cards. What is the probability that each card is a face card. (There are 12 face cards in a deck.) Select the best answer from the choices provided.
A. 0.23077
B. 0.01229
C. 0.00938
D. 0.00995

First card being a face card = 12/52 = 3/13

Second card being a face card = 11/51

Third card being a face card = 10/50 = 1/5

Probability of all three = 3/13 x 11/51 x 1/5 = 0.00995

The answer is D.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
