Step 1: Find the total number of balls in side the bag

            GIVEN: Number of red balls = 3

                        Number of black balls = 5

                      Total number of balls = 5 + 3 = 8


Step 2: Find the probability of drawing red balls

            Number of favorable outcomes = number of red balls = 3  

        (i) Probability of drawing red balls = \frac{\text{Number of balls}}{\text{ Total number of balls}} = \frac{3}{8}


Step 3:  Find the probability of drawing not red balls

            Number of favorable outcomes = number of not red balls = number of block balls =  5  

        (ii) Probability of drawing black balls = \frac{Number\ of\ block\ balls}{Total\ number\ of\ balls}=\frac{5}{8}
