How many dots on two dice

  1. 20

  2. 24

  3. 40

  4. 42


Correct Option: D

AI Explanation

To answer this question, we need to understand that each die has six faces, numbered from 1 to 6.

To find the total number of dots on two dice, we need to consider the possible combinations of numbers that can appear on each die.

On one die, the total number of dots is the sum of all the numbers on its faces, which is 1+2+3+4+5+6 = 21.

Since we have two dice, we can multiply the total number of dots on one die by 2, which gives us 21*2 = 42.

Therefore, the correct answer is D) 42.
