Pr = ways_of_success/total_ways

Pr(Red) = 3/(5+3+1) = 3/9

Pr(Green) = 1/9

As they are independent:

Pr(Red or Green) = Pr(Red) + Pr(Green) = 3/9 + 1/9 = 4/9

----------------------------------------------------

Alternatively, as there are only three colours, selecting either Red or Green is the same as not selecting Blue:

Pr(Red or Green) = Pr(not Blue) = 1 - Pr(Blue)

→ Pr(Red or Green) = 1 - 5/9 = 4/9

The probability of choosing a blue marble is 5 in 15 or 1 in 3. The probability of then choosing a green marble is 5 in 14. (One is missing) Multiply the two probabilities and you get 5 in 42.(P = 0.1190... about 12%).

What is the experimental probability of choosing a green marble if there are 7 red 9 yellow 14 green and 10 purple?

To find the experimental probability of choosing a green marble, first calculate the total number of marbles: 7 red + 9 yellow + 14 green + 10 purple = 40 marbles. The probability of choosing a green marble is the number of green marbles divided by the total number of marbles, which is 14 green / 40 total = 0.35. Thus, the experimental probability of choosing a green marble is 0.35, or 35%.
