Question

/1. You are rolling a pair of dice. What's the probability of getting different numbers on both dice?

Answer 1

5/6

Step-by-step explanation

Probabaility is the likelihood or chance that an event will occur. Mathematically;

Probabiblity = Expected outcome/Total outcome

Since a pair of dice is rolled;

Total outcome for n dice = 6^n

For a pair of dice, total outcome is 6^2 = 36

For the expected outcome

If we got different numbers on both dice, the outcomes wil be 30 since the only periods we will have the same value are [(1, 1), (2,2), (3,3), (4,4), (5,5), (6,6)] which is 6 outcomes

getting different numbers on both dice = 36 - 6 = 30

Probability of getting different numbers on both dice = 30/36

Probability of getting different numbers on both dice = 5/6
