Question

A bag contains 3 red balls, 4 blue balls and 1 yellow ball, all the balls being identical in shape and size. If a ball is taken out of the bag without looking into it; find the probability that the ball is:

red

Solution

Total number of balls in the bag=3+4+1=8 balls

Number of possible outcomes=8=n(s)

Event of drawing a red ball ={R,R,R}

n(E)=3

Probability of drawing a reddd ball=(n(E))/(n(S))=3/8

Is there an error in this question or solution?
