a fair coin is tossed in the air 4 times. if the coin lands heads up the first three tosses, what is the probability the coin will land heads up the fourth toss?

I think it is 1/2 because the coin has 2 sides and 50% it will land on heads.

My friend thinks it is 1/16, since each toss is 1/2, so 1/2 *1/2*1/2*1/2=1/16 since you mult each toss

Am I correct or is my friend?

Thanks for the help
