Morgan Blackburn · Answer 1

When flipping a coin 3 times there are eight possible outcomes:

H H H

H H T

H T H

T H H

H T T

T H T

T T H

T T T

In four of those instances you have at least 2 tails. Therefore, the chance is 50%.

Dulce Bullock · Answer 2

Flipping a coin is an independent event, meaning the probability of getting heads or tails does not depend on the previous flip. It's 1/2 or 0.5 chance every time.

So three coin flips would be = (0.5) * (0.5) * (0.5)

= 0.125

* 100%

= 12.5% chance
