The question is number 9.

[Difficulty]
I'm just unsure about b(2) and (3) and (4). Think I've done them wrong....

[Thoughts]
I'm not sure if b(2) is 1/4 or a half, I think (3) is a 1/2 and (4) is a 1/4. please could someone confirm my answers?

Thank you very much! :D
 
Once again my computers only show part. In this case only the middle.
b) I assume that there are the same number of each suit.

b1) correct !/2 that the first is one of them * 1/4 the second is the other = 1/8

b2) correct. 1/2 first is red * 1/2 the second is red = 1/4

b3) b3 I can't read your answer.
1/1 the first is some color * 1/2 the second is the same color = 1/2

b4) correct. 1/1 the first is some suit * 1/4 the second is the same suit = 1/4
