Question

if a toss coin 3 times and gets head each time should a expect tail in 4th chance?give reason

Answer 1

If the coin toss is fair, then probability of getting heads is 1/2.
If the coin gives heads thrice, there is a very high chance that the fourth could be tails.
U know, to balance the probability of the universe ;-)

Answer 2

Since any toss does not affect or influence the outcome of any other toss, the probability of getting a head or a tail is the same 1/2.
The key take away point is that all coin flips are independent events (which applies to many random events). That is, the second coin toss result isn't affected by the first. How could it be? A coin has no mind or memory! It doesn't know, nor does it care, that it has already been flipped and what the outcome was.

Hope this will help you.
