Question

Determine the probability that a digit chosen at random from the digits 1, 2, 3, …12 will be odd.

Answer 1

Answer:

5/11

Step-by-step explanation:

no.of odd numbers=5

total no. of digits=12

probability=5/12

Answer 2

Probability

For finding the probability of choosing a digit randomly from 1, 2, 3, 4,5,6,7,8,9,10,11, 12, we need to follow the formula i.e.

$probability = \frac{number \ of\ favourable\ outcome}{Total \ number\ of \ outcomes}$

In this case favorable event is choosing the outcome,

So among given numbers,  odd numbers are 1,3,5,7,9,11.

So, number of occurrence of favorable outcome is 6.

Hence, probability is  $\frac{6}{12}=\frac{1}{2}$  .

So, probability that a digit chosen at random from digits will be odd is  1/2.
