Question:

Three dice are thrown together. Find the probability of getting a total of at least 6.

Options:

$\frac{5}{108}$

$\frac{5}{18}$

$\frac{101}{108}$

$\frac{103}{108}$

Correct Answer:

$\frac{103}{108}$

Explanation:

The correct answer is Option (4) → $\frac{103}{108}$

If three dice are thrown, total sample space =216

 

The event of getting the sum less

than 6 =1,1,1,1,1,2,1,2,1,2,1,1,1,2,2,2,2,1,2,1,2,1,1,3,3,1,1,1,3,1

 

Since the number of outcomes, in which the sum less than 6 is 10.

 

The probability of getting a total less than 6 =10 / 216

 

Therefore, the probability of getting a total of atleast 6 =1-10/216

 

The probability of getting a total of atleast 6 =103/108

 

Hence option D is the correct option.
