How can I solve this?
It is known in the ice-cream industry that 38% of people have chocolate as their favourite flavour of ice-cream.
Let X be the number of people in a sample of 10 who say chocolate is their favourite ice-cream flavour.
Find P(X < 3)
Do I need to use the probability tree to list all the probability out?
