-If you pick one marker at random, what is the probability that the marker is NOT Green?

If you pick one marker at random, what is the probability that the marker is Blue OR Yellow?

Answer 1

P(Red) =
`(12)/(50)` =
`(6)/(25)`

P(not green)

= 1 -
`(8)/(50)`

=
`(21)/(25)`

P(Blue or yellow)

= P(Blue) + P(Yellow)

=
`(7)/(50)` +
`(9)/(50)`

=
`(8)/(25)`
