A letter is chosen at random from the letters in the word PROBABILITY . What is the probability that tha letter will be
B

Answer

To find the probability of randomly selecting the letter 'B' from the word "PROBABILITY", we can follow these steps:

### Step 1: Count the total number of letters in the word "PROBABILITY".
The word "PROBABILITY" consists of the following letters: P, R, O, B, A, B, I, L, I, T, Y.

**Total letters = 11**

### Step 2: Count the number of times the letter 'B' appears in the word.
In the word "PROBABILITY", the letter 'B' appears twice.

**Number of 'B's = 2**

### Step 3: Calculate the probability of selecting the letter 'B'.
The probability (P) of an event is given by the formula:

\[ P(\text{event}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]

In this case, the favorable outcome is selecting 'B', and the total outcomes are the total letters in the word.

So, the probability of selecting 'B' is:

\[ P(B) = \frac{\text{Number of 'B's}}{\text{Total letters}} = \frac{2}{11} \]

### Final Answer:
The probability that the letter chosen will be 'B' is \( \frac{2}{11} \).
