Question
Discrete Math and probability answer A please
a) There is a donut shop with 4 types of donuts. (A, B, C, D} What is the probability
that a random sale of 12 donuts contains at least 6 donuts of type A? Assume all sales
are equally likely.
b) What is the probability that 2, unfair, six-sided dice have a sum of at least 10? Let
the probability distribution for both dice be: P(d1 = x) = , e.g. the probability of a
dice rolling a 3 is
3
