Question

a fair coin is tossed 3 times. What is the approximate probability of heads apppearing atleast one time

Answer 1

Possible outcomes of a coin toss are a head or a tail.

Since the coin is tossed three times, there'll be six possible outcomes.

• H - heads
• T - tails

H H H T T T - Possible outcomes

The possibility of a head appearing at least once is therefore 1/3.

Hope it helps. :)
