When multiplying polynomials for a math
assignment, Alexis found the product to be
- 4x + 8x^2 - 2x^3 + 5. He then had to state the
leading coefficient of this polynomial. Alexis
wrote down -4. Do you agree with Alexis's
answer Explain your reasoning.

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100
