(iv) 'six' in two dice.
​

Answer 1

Step-by-step explanation:

That's a total of 26 outcomes (two-dice rolls) that sum 6 or greater. The entire sample space, or the total number of possible roll outcomes, is 36. Therefore, the probability of rolling 6 or greater with two dice is the number of favorable outcomes (26) divided by the total number of outcomes (36): 26/36, or 13/18.
