A loaded coin is tossed 5 times, find the probability distribution for the number of heads, if heads are thrice likely to occur than tails. Let x be the number of heads that will turn up. Compute the probability associated to each value of X using the equation:
x=0,1,2,3,4,5
P(X=x)= (5/4)(3/4)x(1/4)5-x note x and 5-x outside () are superscripts there..
