1,200 because 4x 3 is 12 and 40 x 30=1,200
C because u can split it only once vertically but it’s not a rotationally symmetrical shape
The probability of having a 17 is the number of ways of having 17 divided by the number of different possible outcomes.
Ways of having 17:
Die 1 Die 2 Die 3 sum
6 6 5 6+6+5 = 17
6 5 6 6+5+6 = 17
5 6 6 5+6+6 = 17
Those are the only 3 possibilities of having 17 (you can only loose 1 point).
The total number of outcomes are 6*6*6 = 216
So the chances (probability) to win is 3 / 216 = 1/72 = 0.0139
-5 because the variable is x and a coefficient comes before the variable.
Hope this helps!
