Luis has a coin that is weighted so that the probability that Heads appears when it is tossed is 0.55. Suppose that the coin is tossed 3 times. What is the probability that all 3 tosses are Heads?
please help ,e to solve this question .
i dont'know if i +am right
.55/2+.55/2+.55/2= 1.65/2 =0.82 Answer
Am i right ?
no, the prob of three heads with that coin
= (.55)(.55)(.55) = appr .166
why are you dividing by 2 ???
Didn't your answer seem illogical to you?
