I have less than 24 hours to find the binomial probability of P(20 23)= if n=30 p=.23 u=6.9 q=.77 and the standard deviation is 2.3 can someone please show me how to get the outcome they want?

I have less than 24 hours to find the binomial probability of P(20<x<23)=

and P(x>23)= if n=30 p=.23 u=6.9 q=.77 and the standard deviation is 2.3 can someone please show me how to get the outcome they want?
