The probability that a two-digit number selected at random has a tens digit less than its units digit is 0.2667 (4/15).
There are 90 two-digit numbers (99-9). Of these, six numbers are divisible by 15 (15, 30, 45, 60, 75, 90). This is also divisible by 5. Therefore, the preferred case is 30-6 = 24. Therefore, the required probability is 24/90 = 4/15.
The probability of an event can be calculated by simply dividing the number of favorable results by the total number of possible results using a probabilistic expression. Whenever you are uncertain about the outcome of an event, you can talk about the probability of a particular outcome, that is, its potential.

Expression simplified: 
Step-by-step explanation:
The expression that we have in this problem is:
The first type of operation that we have to solve in such expression are multiplication/division.
In this expression, there is only one multiplication, that is:
So we can rewrite the expression as
Now we can evaluate the sum of the similar terms: in this case, similar terms are only 3 and 4, and their sum is
Therefore, the expression can be rewritten as
