KnowledgeBoat · Accepted Answer

The numbers are chosen from 10 to 99 inclusive. Total number of outcomes = 90 Let E be the event of choosing a number with At Least One Digit as 8 , then E = {18, 28, 38, 48, 58, 68, 78, 88, 98, 80, 81, 82, 83, 84, 85, 86, 87, 89} The number of favorable outcomes to the event E = 18 P(E) = Hence, option 1 is the correct option.
