statistics prob distribution help maths a level

[latent cliff]

this question was on the maths as level stats paper last year, found it hard due to it being layed out differently than normal

ok, so you basicly have to make a table to show how likely it is to get X about of A's by selecting three times

since there are only 2 A's in Variance, you can only pick zero, one or two A's
