Q13 of 96 Page 161

If I toss a coin 3 times and get head each time, should I expect a tail to have a higher change in the 4th toss? Given reason in support of your answer.

No, let we toss a coin, then we get head or tail, both are equally likely events. i.e., probability of each event is 1/2 .So, no question of expecting a tail to have a higher change in 4th toss.
