Prob to get 2 heads = 1/2*1/2 = 1/4
Prob to get 2 tails = 1/2*1/2 = 1/4

So, Prob to get either 2 heads or 2 tails = 1/4+1/4 = 1/2

Answer will be D.

A. 1/8
B. 1/6
C. 1/4
D. 1/2
E. 1


The first probability to get anything after toss is 1
The second probability to get the same side of the coin is \(\frac{1}{2}\)

\(1 * \frac{1}{2} = \frac{1}{2}\)
