show work pls tnx!

Answer 1

Answer:

2/3

Step-by-step explanation:

7 red, 5 yellow, and 6 orange  =18

P( red or yellow) = number of red or yellow / total

                           = (5+7)/18

                             =12/18

                             =2/3

Answer 2

Answer:

p(r or y) = 2/3

Step-by-step explanation:

Total no. of gumballs = 7 (red) + 5 (yellow) + 6 (orange)

= 18 gumballs

p(r or y) = no. of red gumballs + no. of yellow gumballs/total no. of gumballs

= (5 + 7)/18

= 12/118

= 2/3

Hope this helps!
