Independent Event Happening Twice

Collapse Content

Probabilities of events happening are easy to study when each event is independent of the other events. To calculate the probability for two events happening, you can multiply the different probabilities together. For example, given a balanced coin, the probability of flipping it and getting heads is 50% each time.


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

  • guys, 1/4 and 25% are both correct and were marked as incorrect. Either provide more detail on format for answers, or make the evaluation function smarter.

  • @Cart, I added text that explains if an exact answer is needed for the question or if a 'math answer' (like 1/4 or 10!) is good too.
