Find the discriminant and determine the nature of the roots to the quadratic equation

(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

What is a possible solutions of the x> 3?

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180
