I know how to calculate the probability of rolling a 6 on a standard 6-sided die 3 times out of 3 etc. What I can't remember how to calculate is this:
If I were to roll TEN dice what is the probability that I would roll a 6 on:
a) EXACTLY 3 occasions
b) AT LEAST 3 occasions
If anybody can help me I would be grateful. Many thanks!
