if a fair coin tossed 4 times .what is the probability the two heads and two tails will result

• coin toss 4 times sample space 2^4
  favourable outcomes are HHTT HTHT THTH TTHH HTTH THHT ie 6
  
  so the probability is 6/16 ie 3/8
  
  another solution is by applying binomial theorm
  
  4C2 (1/2)^2 X(1/2)^2 = 3/8
