A coin that is tossed will land heads or tails, and each outcome has equal probability. What is the probability that the coin will land heads at least once on two tosses???
a)1/4
b)1/3
c)1/2
d)2/3
e)3/4
The way I approach this is (first toss will 1/1 is 1. (seocond toss) will be 1/2
so 1*1/2 is 1/2
OA is E ,why
