A single die is rolled on time. Find the probability of rollung a number greater than 5 or less than 4​
suter [353]

Answer:

\dfrac{2}{3}

Step-by-step explanation:

A single die is rolled on time.

All possible outcomes are 1,2,3,4,5,6 (6 in total)

Rolling a number greater than 5 or less than 4​ means rolling numbers 6 or 1,2,3 so

All favorable outcomes are 1,2,3,6 (4 in total)

The probability of rolling a number greater than 5 or less than 4​ is

P=\dfrac{\text{Number of all favorable outcomes }}{\text{Number of all possible outcomes}}\\ \\=\dfrac{4}{6}\\ \\=\dfrac{2}{3}
