# An unfair coin

**Discrete Mathematics**Level 5

For an unfair coin, if \(E(HH) = E(T)\), then what is \(E(T)\) to 3 decimal places?

**Clarifications**:

\(E(HH) \) denotes the expected value for the number of flips you would make before flipping 2 heads in a row

\(E(T) \) denotes the expected value for the number of flips you would make before flipping a tail.
