Is 100 a solution because it is much greater than 35. True or false

Umm.. just started this 2day and its not on my notes(p′︵‵。)

3. find the radius of circle p.4. find y.

(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
