Question

you have a big bag of 17 marbles for our blue sticks are green 2 are red and the others are yellow what is the probability of drawing a red marble putting it aside and then drawing a green marble?

Answer 1

• 3/68

Explanation:

Given

• Total 17 marbles
• 4 - blue marbles
• 6 - green marbles
• 2 - red marbles
• The rest - yellow marbles

Probability of drawing red first:

• P(red) = number of red / total number = 2/17

Probability of drawing green second, without replacement:

• P(green) = number of green / number left in the bag = 6/16 = 3/8

Probability of red and green in order:

• P = P(red)*P(green) = 2/17*3/8 = 3/68
