1.) P( green or red ) = 11 /18

2.) P ( grapes and bnaa ) = 17 / 30

Step-by-step explanation:

1 .) Probability of boy picking a green or red bior closing his eyes

= 5 + 6 / 5 + 7 + 6

P( green or red ) = 11 /18

2.) Probability of that the fruit is either a grape and banana , P ( grapes and banana)

P ( grapes and banana ) = 6 + 11 /6 +11 +13

P ( grapes and banana ) = 17 / 30
