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 t he probability that it is Green is 0.4 Find the probability that ball selected is: the selected balls are yellow and not red

Answer:
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
