It is the binomial type probability distribution problem.



The number of trial n= 100; the probability of the success trial is  2% = 0.02,  and the number of success trial k = 2. 


P = C%5B100%5D%5E2%2A0.02%5E2%2A%281-0.02%29%5E98 = %28%28100%2A99%29%2F%281%2A2%29%29%2A0.02%5E2%2A0.98%5E98 = 0.2734.     ANSWER

Solved.
