Assume that each of the n trials is independent and that p is the probability of success on a given trial. Use the binomial probability formula to find P(x). P(x)= _ n=19, x=3, p=1/4 (Round to three decimal points as needed.)
Added by Brenda D.
Step 1
Now, we can plug in the given values into the formula: P(3) = C(19, 3) * ((1/4)^3) * ((1 - 1/4)^(19 - 3)) Show more…
