Question

A dice is rolled once. What is the probability of getting : <br />a) a 3 ?<br />b) an even number ?​.​

Answer 1

Answer:

$\huge\underline\bold {Answer:}$

a) Number of 3’s on a dice = 1

Total number of possible outcomes = 6

(Since Sample space = {1, 2, 3, 4, 5, 6})

Therefore probability of getting 3 = 1/6.

b) Number of even numbers on a dice

= 3(2, 4, 6)

Total number of possible outcomes = 6

Therefore probability of getting an even number

= 3/6 = 1/2.
