Question

The probability of getting total at most '6' when three cubical dice are thrown is _____.

• A. 5/54
• B. 5/72
• C. 5/36
• D. 5/216

Answer 1

The correct option is A 5/54

Probability shows the relationship between two variables in the form of ratio, percentage or proportion where there the chances of occurrence of one variable is expressed in terms of the other variable which is usually sample space.

The sample space for the given problem is 6x6x6 = 216

Let the required event be E ( getting a total of at most '6')

n(E) = 20

Therefore, P( getting a total of at most '6') = n(E)/S

= 20/216

= 5/54
