4. ### How do you prove C(n + 1, r + 1) = C(n, r) + C(n, r + 1)?

c(a , b) = a! / (b! * (a - b)!) C(n + 1 , r + 1) => (n + 1)! / ((r + 1)! * ((n + 1) - (r + 1))!) => (n + 1)! / ((r + 1)! * (n + 1...r + 1) * r! * (n - r)! / (n - r)) => n! * (n - r) / ((r + 1) * r! * (n - r)!) => (n - r) / (r + 1) * (n! / (r! * (n - r)!)) (1 + (n - r) / (r + 1)) * (n! / (r! * (n - r)!)) =>...
