5s - 6 = 2s, ie 5s - 2s = 6, ie 3s = 6, ie s = 2
Use four 5's to make 6
6/6 +6/6=2
If the dice are fair, it is (1/6)4 = 1/1296
3x3=9... 9-3=6.... 6/3=2 !
Yes
Well, isn't that a happy little puzzle! You can use a combination of a half dollar (50 cents), a quarter (25 cents), a nickel (5 cents), and three pennies (3 cents) to make a total of 80 cents. Just remember, there are many different ways to solve a problem, so feel free to get creative and explore different combinations!
( 6 / 6 ) * (( 6^2) + 6 ) = 42 1 * ( 36 + 6 ) = 42 1 * 42 = 42 42 = 42
You don't say how many 6s I'm allowed to use, but here it is with four of them: 6 ÷ 6 + 6 + 6 = 13
6*7
The answer is 9C4 = 9*8*7*6/(4*3*2*1) = 126 ways.
