The probability of getting a head when a biased coin is tossed is . The coin is tossed three times. Find the following probabilities and select the correct solution. P(three tails) = . P(two tails followed by one head) =

How would you solve this?? How would uu find the probabilities??
SmokeyBrown:
For the first part "The probability of getting a head when a biased coin is tossed is ." are you given the probability of getting a head, or is that part actually blank?
SmokeyBrown:
If you're given the probability of Heads (we can call that PH), we can find the probability of getting Tails (PT = 1 - PH), since those are the only two possibilities. If we have the probability of getting tails (PT), then the probability of getting 3 consecutive tails would be PT*PT*PT. In a similar way, the probability of getting 2 tails followed by 1 head would be PT*PT*PH
