Given that A bag contains $3$ red, and $5$ black balls. A ball is drawn at random
to find: Probability of getting a
(i) red ball
(ii) white ball
So, Total number of balls $3+5=8$
(i) we know that Total number red balls are $3$
We know that the Probability = Number of favorable outcomes/ Total number of outcomes
Therefore, the probability of drawing a red ball $=3/8$
(ii) Now Total number of black balls are $5$
We know that the Probability = Number of favorable outcomes/ Total number of outcomes
Hence, the probability of drawing a black ball $=5/8$
