The mean is μ=np=2417=8170.4706 and the standard deviation is
σ=np(1p)=24171317=1042890.5999
Explanation:
The special formulas μ=np and σ=np(1p) only work for binomial random variables, where n is the number of independent trials with outcomes success or failure, and p is the probability of success on each trial. The random variable X itself counts the number of successes in n trials.
