Tell whether or not the trials of drawing balls are Bernoulli trials when after each
draw the ball drawn is
(i)
replaced
(ii)
not replaced in the urn Solution
(i)
The number of trials is finite When the drawing is done with replacement, the
probability of success (say, red ball) is  p = 7
16  which is same for all six trials
(draws) Hence, the drawing of balls with replacements are Bernoulli trials
