Answer 1

Answer:

AS the coin flips are independent events, the probability for multiple of a result is the probability of each individual result multiplied.

So, since the probability of one coin flip being Heads is 1/2 (assuming a fair coin), the probability of 3 coins being Heads is (1/2)^3 or 1/8.

The probability of Tails is exactly the same.

So, 1/8 + 1/8 = 2/8 or 1/4.
