HELP ME ON MATH

1. The letters for the word MATH are placed in a bag. Two letters are selected with replacement. Which statements are true about the tree diagram that could represent the possible outcomes? Select TWO that apply.

a. There would be 4 tree bases.
b. Each base would have 3 tree branches.
c. The diagram would show a total of 12 possible outcomes.
d. There would be 4 combinations that have double letters.

I think it's A and D

2. A spinner has three equal sections labeled 1, 2, and 3.

What is the probability of getting two numbers that have a sum of 5 on the spinner?

a. 2/9
b 1/3
c. 1/6
d. 4/9

I think it's B, but I'm weighing in more with A.

Please correct me on both IF I'm wrong!

  2. #1 ok

    #2
    There are 9 possible outcomes:

    11 12 13 22 21 23 31 32 33

    So, how many of those add up to 5?
    Looks like P=2/9 to me.
