Question

What is the probability of not drawing a green marble from a jar containing 7 red, 4 green, 3 white, and 9 blue marbles?

Answer 1

Probability of not drawing a green marble is 19/23.

Explanation:

A jar is containing 7 red, 3 white, and 9 blue marbles.

Then the probability to draw a green marble will be = Numbers of green marbles/ Total numbers of marbles of all colors

P(G) = 4/(7 + 4 + 3 + 9)

P(G) = 4/23

Now the probability of not drawing a green marble = 1 - probability of drawing a green ball

P = 1 - 4/23 = 19/23

Therefore answer is 19/23.

Answer 2

`7+4+3+9`

`11+12`

`23`


`(23)/(23) - (4)/(23)`


`(23-4)/(23)`


`(19)/(23)`
`chance`
