Answer 1

Answer :

Probability outcome = 1 / 90

Step-by-step Explanation :

Given : Teacher asked students to say a two digit number.

To find : The probability of that number being 17 = ?

We know that ,

Probability outcome = No. Of favourable outcomes / Total No. Of outcomes

Total Number of outcomes = 99 - 9 = 90

( Since all two digit are from 11 to 99 )

Also,

Number of Favourable outcomes = 1 ( i.e getting no as 17 )

Substituting the value in above formula we get,

Probability outcome = 1 / 90
