anonymous · Answer

1 out of 5 plus 1 out of 5 = 2/5

anonymous · Answer

looks too easy. what part isn't clear?

anonymous · Answer

I was just confused do you count the blue and green together as one or no?

anonymous · Answer

there are three primary colors, Red Blue and Green

there are five possible outcomes,

the probability of a primary color is 3 / 5

??

anonymous · Answer

That makes sense. Thanks!

anonymous · Answer

the answer is 2/5 not 3/5

when a problem says probability of 'this OR that' - usually you add the individual probabilities. its a basic theorem.  Another way -  P(blue or green)  is the same as if the bag had (red, orange, yellow, blue, blue) and you had to find P(blue)
