Answer:
an ordinary die has numbers from 1 to 6
Number of dots on the face = number that face represent
Dots on face can be 1 , 2 , 3 , 4 , 5 , 6
1. Number of 3 Dots
Probaility = 1/6
2. Number of Dots less than 3 = 1 or 2 Dots
Probability = 2/6 = 1/3
3 . An even number = 2 , 4 , 6
Probability = 3/6 = 1/2
