Question

An ordinary die is rolled, what is the probability that the number of dots on its upper face is 3

Answer 1

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
