Question

The probability of selecting a particular color almond m&m (according to the website) from a bag of m&ms is listed below. let the probability of selecting a color be represented as br= brown, y= yellow, r= red, bl = blue, o= orange and g = green. a probability distribution is listed below. brown yellow red blue orange green probability 0.1 0.2 0.1 0.2 0.2 0.2 suppose that you randomly select one m&m. what is the p(r or br)?

Answer 1

Answer: P(r or br) = 0.2

Explanation: When two events are mutually exclusive, i.e., they can happen at the same time, the probability of event A occur OR event B occur is given by the sum of the probability of each one.

The question asks for the probability of selecting Red, P(r), or selecting brown, P(br). So:

The probability of Red:

P(r) = 0.1

The probability of Brown:

P(br) = 0.1

The probability of Red OR Brown:

P(r or br) = P(r) + P(br)

P(r or br) = 0.1 + 0.1

P(r or br) = 0.2

The probability of choosing Red or Brown is 0.2.
