Best ResponseYou've already chosen the best response.1Nope. If u ! after a number u call it as factorial. 3!=3*2*1 similarly 4!=4*3*2*1

Best ResponseYou've already chosen the best response.1Do you know that\[3!= 3\times2 \times 1\\ 4! = 4\times3 \times 2\times 1\]And so\[\dfrac{\color{#C00}{3!}}{4!} = \dfrac{\color{#C00}{3\times2\times1}}{4\times3 \times 2\times1}\]

Best ResponseYou've already chosen the best response.0Use a calculator. But it is pretty clear it is 1/4 or 0.25

Best ResponseYou've already chosen the best response.0The exclamation mark means factorial. In this case 3! Is (3 x 2 x 1) If It was let's say, 6! It would be (6 x 5 x 4 x 3 x 2 x 1) So in your question 3!/4 is 3x2x1 divided by 4 which is 6 divided by 4, which is 0.75 :) glad I could help.

Best ResponseYou've already chosen the best response.0Oh, then it's (3 x 2 x 1) / (4 x 3 x 2 x 1) Which is 6 / 24, meaning the answer is 0.25? :)
