Peanut butter m&ms manufactured. 10% each are brown and red. 20%each yellow, blue and orange. The rest green

Question

What is the probability if chosen at random that you will pick green? That it is red, yellow or blue? That it is not orange?

Answer 1

P(Green) = 1 - P(Any other color) = 1 - (.10 + .10 + .20 + .20 + .20) = 1 - .80 = .20

 

P(Red, Yellow, Blue) = .10 + .20 + .20 = .50

 

P(Not orange) = 1 - P(Orange) = 1 - .20 = .80
