Question

A number cube with faces labeled 1 to 6 is rolled once. The number rolled will be recorded as the outcome. Consider the following events.
Event A: The number rolled is less than 5.
Event B: The number rolled is even.

Answer 1

Guessing that you are looking for the probability, event a-4:6 even b-3:6

Answer 2

Answer:

When a Die is rolled once possible outcomes are={1,2,3,4,5,6}=6

→ Favorable Outcome , the number rolled is less than 5={1,2,3,4}=4

 Probability of number getting less than 5 will be

           $=\frac{\text{Total Favorable Outcome}}{\text{Total Possible outcome}}\\\\=\frac{4}{6}\\\\=\frac{2}{3}$

→ Favorable Outcome , the number rolled is even=Multiple of 2 ={2,4,6}=3

       Probability of Rolling even number is,

           $=\frac{\text{Total Favorable Outcome}}{\text{Total Possible outcome}}\\\\=\frac{3}{6}\\\\=\frac{1}{2}$
