If a coin has an equal probability of landing heads up or tails up each time it is flipped , what is the probability that the coin will land heads up exectly twice in 3 consecutive flips ?	Pick
A) 0.125	B) 0.25	C) 0.375	D) 0.5	E) 0.666
P=nCm*p^m*q^(n-m)   n - the total number of trials.   m - the number of trials with heads.   n-m - the number of trials with tails.   p - probability of heads.   q - probability of tails.   P=30.3752*(1/2)^2*(1/2)^1=3/8=
