Could someone help me figure this out? I'm a bit stuck. A classmate was to simplify the rational expression below and write the answer in root form.

(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

Write an equation for the function that includes the points (2,100)and (3,100)

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.
