The simplest method is------- --2^(n)---- where n is the number of times coin is tossed.... Now write in this way------ 2^(n)/2 times H | 2^(n-1)/2 times H | same....... 2^(n)/2 times T | 2^(n-1)/2 times T | same....... For example---------- -------------------coin is tossed 3 times------------------- 2^(3)= 8 ------------------------------------------------------------------------- H H H H H T H T H H T T T H H T H T T T H T T T -----------------?? Ok????---------------------------------
