Question

given the table of M&M distributions below , P(not blue), the probability of selecting anything but blue M&M at random from a large bag
RED 0.13 ORANGE 0.20 YELLOW ? GREEN 0.16 BLUE 0.24 BROWN 0.13

Answer 1

Well you can do this by using complementary events

P(not blue) = 1 - P(blue)

Answer 2

HOW @campbell_st

Answer 3

well you are given the probability of selecting a blue M & M

P(blue) = 0.24

the maximum probability is always 1

so you have 2 options for finding the probability of not blue

1. add up the probabilities of all the other colours

2. use complementary events

P(not blue) = 1 - P(blue)
= 1 - 0.24

you'll get the same answer with either method..

Answer 4

SOO I JUST DO THIS 1-0.24=0.76 @campbell_st

Answer 5

that's it

when I do the not probability questions I always use

P(not ?) = 1 - P(?)

its just easier
