If you just needed the points on the graph here it is! :) hope this helped !!
Large box 70, small 55
x+y=125
40x+20y=3900
y=125-x
40x+20(125-x)=3900
40x+2500-20x=3900
20x=1400
x=70
125-70=y
y=55
The probability of rolling a 2 is 1/6. So if you roll 8 times you would expect to roll a 2:
8(1/6)=8/6=1 1/3 times.
The answer would be A.
Because you are subtracting the exponents.
Hope it helps.
