Default can someone please explain the binomial probability distribution to me please?

i have a statistics exam tomorrow and i still dont understand this! i have a past exam paper and a question on binomial probability distribution is: megan throws darts at a target she can hit the target with 7 out of 9 throws. megan throws 3 darts. assuming a binomical distribution, work out the probability that she hits the target exactly twice. you may use (p+q)^3=p^3+3p^2q+3pq^2+q^3please help if you can!
