odds against drawing a Jack are 48:4
odds in favor of drawing a Jack are: 4:48
Use the binomial expansion formula for (a+b)^n
(sorry, cannot type it here, please google)
n!/[(n-k)!k!]a^(n-k)b^k
x^6y^3 is when k=3
in this case, n=9
so the coefficient when k=3 is: 9!/[(9-3)!3!]*(2)^3=
B)32
8(4) means to multiply 8 and 4. 8 x 4 = 32
Infinite solutipn is the answet
