Question

A fair coin is tossed 4 times. What are the odds against not tossing at least one head?

Answer 1

`1/16` Chance (Based on each side having a 50% chance)

Explanation:

In the real world a normal coin flip is not 50/50 but usually questions like these assume so, so I will too.

On the first flip there is 2 possibilities, heads or tails so that's a
1 in 2 chance or `1/2`
To calculate the chance of the same thing occurring multiple times in a row you put the amount of times in a row as a power to the denominator like this
`1/2^4=1/16`
