Question

You roll a standard number cube. Find P(odd).
A) 5/6
B) 1/3
C) 2/3
D) 1/2

Answer 1

1/2 because there are 3 odd numbers in 6 = 3/6  . simplified: 1/2

Answer 2

`(1)/(2)`

Explanation:

Given : A cube

To Find : Probability of getting odd numbers

Solution :

Numbers on dice = 1,2,3,4,5,6

Odd number on dice = 1,3,5

Thus no. of favorable events = {1,3,5}=3

Total no. of events = {1,2,3,4,5,6} =6

Thus
`\text{Probability of getting odd no.} = \frac{\text { no. of favorable outcomes}}{\text {no. of total outcomes}}`

⇒
`(3)/(6)`

⇒
`(1)/(2)`

Thus the probability of getting odd =1/2

P(odd) =
`(1)/(2)`
