24. P(not red)
25. P(green) =

Answer 1

See below ~

Explanation:

Q23)

• P (blue) = No. of blue marbles / Total marbles
• P (blue) = 12/(50 + 12 + 2 + 10 + 10)
• P (blue) = 12/84
• P (blue) = 1/7
• P (blue) = 0.14

Q24)

• P (not red) = No. of marbles that are not red / Total marbles
• P (not red) = 74/84
• P (not red) = 37/42
• P (not red) = 0.88

Q25)

• P (green) = No. of green marbles / Total marbles
• P (green) = 50/84
• P (green) = 25/42
• P (green) = 0.59

Answer 2

p(blue)=0.14

p(not red)=0.9

p(green)=0.6

Explanation:

p(blue)=12/84=0.14

p(not red)=74/84=0.9

p(green)=50/84=0.6

Hope it helps
