someone throws a 2 six sided cube labeled 1-6. What is the probability that both of the dice will add up to 7?

Question

Two friends are playing a cane in which 2 six-sides cubes, each numbered 1-6, are thrown and the sum of the sides that land face up are totaled. What is that probability that a person throws both cubes and the sum of the face is 7?

Answer 1

Probability is defined as:

   (number of successful outcomes) / (number of possible outcomes).

 

There are 36 possible outcomes (that is, 6*6):   1-1, 1-2, . . . 6-6

 

There are 6 successful outcomes:  1-6, 2-5, 3-4, 4-3, 5-2, 6-1

 

   P(sum of 7) = 6/36 = 1/6
