A fair coin is tossed 3 times. What is the probability of getting at least 2 heads?  Choose the correct choice from the following options:
A) 3/4
B) 3/2
C) 1/4
D) 1/2
E) 1/5
Let's find the probability of 2 heads , 3 heads   P(HHH)=((1/2)^3=1/8.   P(HHT)=(3!/2!)*(1/2)^3=3/8   Total Probablity = 1/8 + 3/8   =1/2   Answer(1/2)
