By using property of probability P(A) = 1-P(not A) A = when sum of dices is at least 4 not A = sum is less than 4 . The only possible option in sum is 3 which is(1,1,1) probability of (1,1,1) occurring P(not A) = \frac{1}{6} * \frac{1}{6} * \frac{1}{6} = \frac{1}{216} P(A) = 1- \frac{1}{216} = \frac...
