Consider a binomial experiment with 20 trials and probability 0.45 on a single trial. Use the binomial distribution to find the probability of exactly 10 successes. Round your answer to the thousandths place
Use the binomial probability function:
P(x) = nCx(p^x)[q^(n-x)]
n = 20
x = 10
p = 0.45
q = 1 - p = 0.55
Substitute into the function and go from there.
You can also use a binomial probability function table with the values listed to find the probability as well. It is an easier way of doing this problem.
I hope this will help get you started.
THis answer is wrong
