For a certain​ candy,15​% of the pieces are​ yellow, 15​% are​ red, 10​% are​ blue,15​% are​ green, and the rest are brown.

​a) If you pick a piece at​ random, what is the probability that it is​ brown?

it is yellow or​ blue?

it is not​ green?

it is​ striped?

​b) Assume you have an infinite supply of these candy pieces from which to draw. If you pick three pieces in a​ row, what is the probability that they are all​ brown?

the third one is the first one that is​ red?

none are​ yellow?

at least one is​ green?

(Round to three decimal places as​ needed.)

An urn has marbles of red, blue, and yellow. There are seven marbles of each of the three colors. The experiment consists of drawing a single, random marble from the urn. Define a random variable X by X(s) = -1 if the marble has red 0, if the marble has blue +1, if the marble has yellow 54 random samples of X are taken. Approximate the probability that the mean of the sample is between 0 and 1/20.

Twelve chairs are to be painted. The available colors are Red, Blue, Green, and Yellow, and every chair must be painted with one color.
