Question

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: i) Yellow ii) Not Red

Answer 1

Answer:

Given :-

• 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.
• the probability that it is Green is 0.4

To Find :-

• Find the probability that ball selected is: i) Yellow ii) Not Red

Solution :-

(I) p(red)+p(yellow)+p(green)=1.

0.35+p(yellow)+0.4=1

0.39+p(yellow)=1

p(yellow)=1-0.39

p(yellow)=0.61

(2) p(red)+p(not red) =1.

0.35+p(not red) =1

p(not red) =1-0.35

p(not red) =0.65
