Question

When rolling two number cubes, what is the probability of rolling a sum that is 6 or a sum that is odd?

Answer 1

Answer:

The Probability is found as:

A) P = 23/36

Step-by-step explanation:

When two dices are rolled, each dice has a total outcomes of 6. The total number of outcomes of both dices is:

$6\cdot6=36$

Find the pair of values (x₁ , x₂) for which sum is 6 or odd number, where x₁ is the number on first dice and x₂ is the number on the second dice.

(1,2),(1,4),(1,5),(1,6),(2,1),(2,3),(2,4),(2,5),(3,2),(3,3),(3,4),(3,6),(4,1),(4,2),(4,3),(4,5),(5,1),(5,2),(5,4),(5,6),(6,1),(6,3),(6,5)

So Desired number outcomes = 23

So, Probability is given as:

P = Desired number outcomes / Total number of outcomes

P = 23/36
