Question

A bag contains 10 red, 6 blue and 4 green jelly beans. If a jelly bean is chosen at random from the bag, what is the probability that it is not blue? A) 1 3 B) 3 10 C) 7 10 D) 7 20

Answer 1

Option C. is the correct option.

Explanation:

A bag contains 10 red, 6 blue and 4 green jelly beans.

A jelly bean is chosen at random from the bag then probability that the ball is blue will be =
`\frac{\text{Total number of blue balls}}{\text{Total number of balls in the bag}}`

P(B) =
`(6)/(20)`

Now we know that probability that the ball picked from the bag is not blue

= 1 - P(B)

= 1 -
`(6)/(20)`

=
`(20 - 6)/(20)`

=
`(14)/(20)`

=
`(7)/(10)`

Therefore, option C. is the correct option.
