Acontainer holds 9 red markers, 13 blue markers, and 17 green markers. you will randomly select two markers without replacement.

a.) fill in the probabilities on each branch of the tree diagram. use the boxes with the fraction bars already provided.

b.) use the tree diagram to answer the following:

• how many ways can you select the markers?

• how many ways can you select exactly 1 blue marker?

• what is the probability that you select 2 red markers?

• what is the probability that you select a green marker and then a red marker?

a.

R9/39B13/38RB

                          G17/38RG

                          R9/38BR

B13/39B12/38BB

                           G17/38BG

                             R9/38GR

G17/39B13/38GB

                              G16/38GG

b).

RB=9/39 × 13/38=3/38

BR= 13/39 × 9/38 =3/38

BG= 13/39 × 17/38=17/114

GB= 17/39 × 13/38=17/114

=3/38 +3/38+17/114+ 17/114 =26/57

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

80 the answer is 80
