A bag contains 3 red balls and 5 black balls. A ball is draw at random from the bag. What is the probability that the ball drawn is red?
: A bag contains 3 red and 5 black balls and a ball is drawn at random from the bag
TO FIND: Probability of getting a
not red ball
Total number of balls `3+5=8`
We know that PROBABILITY =`"Number of favourable event"/"Total number of event"'`
Hence probability of getting red ball is `3/8`
