you can just as easily consider the % values as integers.
Then just count the ones you need, out of 100
According to Masterfoods, the company that manufactures M&M’s, 12% of peanut M&M’s are brown, 15% are yellow, 12% are red, 23% are blue, 23% are orange and 15% are green. [Round your answers to three decimal places, for example: 0.123]
Compute the probability that a randomly selected peanut M&M is not green.
Compute the probability that a randomly selected peanut M&M is blue or orange.
Compute the probability that two randomly selected peanut M&M’s are both orange.
If you randomly select three peanut M&M’s, compute that probability that none of them are orange.
If you randomly select three peanut M&M’s, compute that probability that at least one of them is orange.

Examples
P(not green) = 1 - .15 = ?
Either-or probabilities are found by adding the individual probabilities.
P(blue or orange) = P(blue) + P(orange)
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
P(both orange) = P(orange)^2
P(none orange) = (1-.23)^3
"at least one" = 1, 2 or 3 are orange. Use methods above.
Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
