The probability that the number picked is less than 84 p(A) is:
number of possible events with picked number less than 84/ total number of possible events = 4/7
The complement event of A is that event A does not occur. If the picked number is not less than 84 ( this means is greater than 84 or is 84). The probability of the complement event is:1- p(A)=3/7
Solution: B
