7 Dayo chooses two digits at random, without replacement, from the 9-digit number 113333555.
- Find the probability that the two digits chosen are equal.
- Find the probability that one digit is a 5 and one digit is not a 5 .
- Find the probability that the first digit Dayo chose was a 5, given that the second digit he chose is not a 5 .
- The random variable \(X\) is the number of 5s that Dayo chooses. Draw up a table to show the probability distribution of \(X\).
