Question

Suppose the inside bottom of a box is painted with three colors: one-third of the bottom area is blue, one-sixth is red, and one-half is yellow. If you toss a tiny pebble into the box without aiming, what is the probability the pebble will NOT land on the color blue?

Answer 1

The probability that the pebble will NOT land on color blue is 0.67.

Explanation:

We attribute the box area as the probability of the events.

So the probability of landing in the Red Area is 1/6, the probability of landing in the Blue Area is 1/3 and the probability of landing in the Yellow Area is 1/2.

P(Red)=
`(1)/(6)`

P(Yellow)=
`(1)/(2)`

P(Blue)=
`(1)/(3)`

The probability of landing in NOT Blue area is given by:

P(Not Blue)=1-P(Blue)=
`1-(1)/(3)=(2)/(3) =0.67`
