a bag holds 4 green marbles,3 blue marbles,and 3 yellow marbles.find the probability of the event

Question

you randomly choose a green marble

you randomly choose a yellow marble

(find the probability of the event)

Answer 1

If you mean separate questions:

Bag: 4 green, 3 blue, 3 yellow, 10 total

Probabilty of choosing green = P(green) = 4/10 = 0.4

Bag: 4 green, 3 blue, 3 yellow, 10 total

Probability of choosing yellow = P(yellow) = 3/10 = 0.3

 

If you mean choosing green, then putting it back in the bag, then choosing yellow:

P(green) * P(yellow) = 0.4 * 0.3 = 0.12

 

If you mean choosing green, not putting it back in the bag, then choosing yellow:

P(green) = 0.4

Bag: 3 green, 3 blue, 3 yellow

P(yellow) = 3/9 = 1/3 or about 0.3333

P(green then yellow) = 0.4 * 1/3 = 4/10 * 1/3 = 4/30 or about 0.133333
