A letter is randomly chosen from the word 'SIMILARITY.'

What is the probability that the letter 'I' will be chosen?

A. 10
B. 0.3
C. 3
D. 0.1



Answer :

To determine the probability that the letter 'I' will be chosen from the word 'SIMILARITY', let us follow these steps:

1. Identify the Total Number of Letters in the Word:
The word 'SIMILARITY' consists of 10 letters.

2. Count the Occurrences of the Target Letter:
The target letter is 'I'. Counting the occurrences of 'I' in the word 'SIMILARITY', we find that 'I' appears 3 times.

3. Calculate the Probability:
The probability [tex]\( P \)[/tex] of selecting the letter 'I' is calculated by dividing the number of occurrences of 'I' by the total number of letters.

[tex]\[ P(\text{'I'}) = \frac{\text{Number of 'I's}}{\text{Total number of letters}} \][/tex]

Substituting the values:

[tex]\[ P(\text{'I'}) = \frac{3}{10} = 0.3 \][/tex]

Therefore, the probability that the letter 'I' will be chosen from the word 'SIMILARITY' is 0.3.

So, the correct answer is:
B. 0.3
