Answer:

1)Is it a 0.7 percent chance that green is not going to choosed

2)25

Explanation:

1)Probability of A NOT occuring: P(A') 0.7

Probability of B NOT occuring: P(B') 0.5

Probability of A and B both occuring: P(A∩B) 0.15

Probability that A or B or both occur: P(A∪B) 0.65

Probability that A or B occurs but NOT both: P(AΔB) 0.5

Probability of neither A nor B occuring: P((A∪B)') 0.35

Probability of A occuring but NOT B: 0.15

Probability of B occuring but NOT A: 0.35

2) 5+4+3+5+4+4=25

375/25= 15/6= 2.5 red
