Can you tell me if I have gotten this correct? If not can you tell me what direction I should going to?

For a binomial distribution with a sample size equal to 3 and a probability of a success equal to 0.65​, what is the probability that the sample will contain exactly two ​successes? Use the binomial formula to determine the probability.
The probability that the sample will contain exactly two successes is____.
​(Round to four decimal places as​ needed.)

X~Binomial(3,0.65)
P(X=2) = 3C2 0.65^2 * (1-0.65)^1
= 3*0.65^2 * (1-0.65)
=0.4436
