Question

Find the probability, in simplest form of picking the letter R in the wore LIBRARY

Answer 1

Step 1: Write out the formula for Probability

`\text{Probability}=\frac{Number\text{ of events}}{\text{Total number of events}}`

Step 2: Writing out the data

The number of times R occur in the word LIBRARY is 2.

The total number of alphabets in the word LIBRARY is 7.

Therefore, number of events= 2

Total number of events= 7

`\text{Probability of picking R=}(2)/(7)`
