If using regular dice, the probability is 0 since the minimum sum from four dice is 4.
With one roll of three dice, the probability is 7/8.
The probability of of rolling three ones on three dice is (1 in 6)3, or 1 in 216, or about 0.004630.
The probability is 90/216 = 5/12
If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032
5/216
The probability is 5/16 = 0.3125
50%. There are three dice; each die has 6 faces.
3/18
The probability is 1 and you do not need Matlab to get that answer - only a little bit of thought.
The probability is zero since at most there could be 2 two's.
There are 216 permutations of three dice. Of these, 15 sum to 7. Therefore, the probability of rolling a sum of 7 with three dice is 15 in 216, or 5 in 72, or about 0.06944.111112113114115711612112212312471251261311321337134135136141142714314414514615171521531541551561611621631641651662112122132147215216221222223722422522623123272332342352362417242243244245246251252253254255256261262263264265266311312313731431531632132273233243253263317332333334335336341342343344345346351352353354355356361362363364365366411412741341441541642174224234244254264314324334344354364414424434444454464514524534544554564614624634644654665117512513514515516521522523524525526531532533534535536541542543544545546551552553554555556561562563564565566611612613614615616621622623624625626631632633634635636641642643644645646651652653654655656661662663664665666
a three on a dice is 1/6 and aheads on a coin is 50%
