Question

A die is thrown 20 times and the frequency of the outcomes is as given below:

Outcomes	1	2	3	4	5	6
Frequency	4	3	5	4	3	1

The probability of getting a number greater than 3 is

• A. 0.6
• B. 0.2
• C. 0.25
• D. 0.4

Answer 1

The correct option is D 0.4

Total number of times, a die is thrown = 20
Number of times, the outcome is greater than 3 = 4 + 3 + 1 = 8
$\therefore \text{P(getting a number greater than 3)}=\frac{\text{Number of favourable events}}{\text{Total number of events}}$
$=\frac{8}{20}$
$=\frac{2}{5}$
= 0.4
Hence, the correct answer is option (d).
