Transcribed Image Text:An employee is selected from a staff of 8 to supervise a certain project by selecting a tag at random from a box
containing 8 tags numbered from 1 to 8. Find the formula for the probability distribution of X representing the number
on the tag that is drawn. What is the probability that the number drawn is less than 4?
