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
