Combining Probabilities 2

Collapse Content

In the last question, you were able to multiply the .1 probability of picking a weighted coin with the .8 probability of getting heads to get a .08 combined probability of both events happening. You put the coin back in the bag, and then randomly select a coin again and flip it.


What is the probability that the coin will be both balanced (not-weighted) AND land on heads?

  • You don't specify that the first coin is replaced which would influence the probability of selection of the unbiased coin.
