Question

a bag has red, green and blue marbles. The probability of selecting a red marble is 1/3 and the probability of selecting a green marble is 2/5. Find the probability of selecting a blue marble

Answer 1

I don't give answers sorry.

Explanation:

What you would do is take 1 and subract the two probabilites from it. The equation should be
`1-(1)/(3) -(2)/(5)`. You can find a common denominator by making it both 15.
