The Probability of an event happening is the ratio of the number of ways it can happen to the total number of outcomes:
[tex]P=\frac{\text{Number of favorable outcome}}{Total\text{ number of outcomes}}[/tex]
Since there are five numbers {1,2,3,4,5}, hence, the total number of outcomes is 5.
The probability required is the probability of numbers greater than 2, P(>2).
The numbers greater than two are {3,4,5}. Hence, the number of favorable outcomes is 3.
Substitute these values into the probability formula:
[tex]P(>2)=\frac{3}{5}[/tex]
The third option, 3/5 is the correct choice.
