Question 610717: Suppose we want to determine the (binomial) probability (p) of getting 0 (zero) heads in 5 flips of a 2-sided coin. Using the table [(n/x) * p^x * q^(n-x)]
what values of n, x, and p would we use to look up this probability, and what would be the probability?
Hi,
Note: Use of [(nCx) * p^x * q^(n-x)] below:
P(0 heads in 5 flips)
Note: The probability of x successes in n trials is: where p and q are the probabilities of success and failure respectively.
In this case & q(tails) = 1/2 or .5
nCx = and
P = 5C0(.5)^0(.5)^5 = 1(.5)^0(.5)^5 =
