A bag contains Red, Green and Yellow balls. A ball is taken at random from the bag. The probability that it is Red is 0.35 and the probability that it is Green is 0.4 Find the probability that ball selected is:

the selected balls are yellow and not red

P (Yellow) = 0.25 P (Not Red) = 0.65

Step-by-step explanation:

P (Red) = 0.35

P (Green) = 0.4

(a) Since there are three colours inside the bag

P (Red) + P (Green) + P (Yellow) = 1

0.35+0.4+P (Yellow) = 1

P (Yellow) = 1 - (0.35+0.4)

P (Yellow) = 0.25

(b) In probability, the sum of an event and its complement is 1.

Therefore:

P (Red) + P (Not Red) = 1

0.35+P (Not Red) = 1

P (Not Red) = 1-0.35

P (Not Red) = 0.65
