Is flip a coin rigged?

No. The tool draws each result with crypto.getRandomValues, so heads and tails have the exact same chance every time you flip.

Why do I get the same side several times in a row?

Streaks are normal in random results. In 10 flips, a run of 3 or 4 of the same side is common because each toss is independent.

Why is flipping a coin an example of independent probability?

One flip does not affect the next. Even after five heads in a row, the chance of heads on the next flip is still 50%.

What is the probability of flipping a coin and getting heads?

The probability of getting heads on a single fair flip is 1 in 2, or 50%.
