Answer:

5) 2/5

6) 9/25

7) 8/33

Explanation:

5) P(red) = 1/5

P(pink) = 1/5

P(red or pink) = 1/5 + 1/5 = 2/5

6) total marbles = 12 + 8 = 20

P(blue) = 12/20 = 3/5

P(blue and blue) = 3/5 x 3/5 = 9/25

7) total gumballs = 8 + 14 = 22

P(red) = 14/22

Now total gumballs = 22 - 1 = 21 (comprising 8 blue and 13 red)

p(blue) = 8/21

P(red and blue) = 14/22 x 8/21 = 112/462 = 8/33
