Re: I need some help in S1The tree diagram refers to the removal of each ball and the probability that it is red or yellow(Original post by Grim Rinazyte)

The numbers on the tree diagram are fairly obvious
TBH I am not sure why you think it is complicated
Do you understand what is happening in terms of the 2 bags and the balls?Last edited by TenOfThem; 07-05-2012 at 20:50. -

P(A)
A= 2 balls drawn from bag P are of the same colour.
Which implies only two possible results
red-red, or yellow-yellow
find the probability of the two seperate possibilities and then add them up! -
