SOLUTION: A doctor is using a method of treatment that is thought to be 94% successful. What is the probability that there are five failures in 15 treatments (round to the nearest thousandth
Hi
Note: The probability of x successes in n trials is:
P = nCx* where p and q are the probabilities of success and failure respectively.
In this case p = .94 and q = .06
nCx =
P(5 failures in 15 treatments) = 15C5(.06)^5(.94)^10
