See a solution process below:


The second and third tosses are independent of the first toss so they are not relevant to this question.

There are 2 possible outcomes of the first toss of the coin: Heads or Tails.

Heads is 1 of 2 possible outcomes.

Therefore the probability of getting a Head on the first toss is"

#1# in #2# or #1/2# or #50%#
