a and b are two numbers selected randomly from 1,2,3.... 25 what is the probability of a and b are not equal. Pick one: A) 24/28 B) 24/25 C) 24/209 D) 22/43 E) 24/19
Explanation:   Total outcomes = 25 × 25 = 625   Probability of getting a and b are equal= 25 [ ∴ (1,1),(2,2),(3,3).....(25,25)]   Probability of a and b or not equal = 1−256251−25625 = 600625600625 = 24/25   Answer: 24/25
