Answer 1

e. 0.308.

Explanation:

I can't draw the tree diagram but the answer is

P(red first) = 7/14 = 1/2

P( then black) = 4/13

P(red then black) = 1/2 * 4/13 = 2/13

P(black first) = 4/14 = 2/7

P( then red) = 7/13

P(black then red) =2/7 * 7/13 = 2/13

So Probability of red and black in any order

= 2/13 + 2/13 = 4/13

= 0.308.
