The probability that Maria draws two B's is 1/55.

How to determine the probability of drawing two B's.

Given

The word PROBABILITY

Total number of letter = 11

The probability of drawing two B's is determined by the ratio of the favorable outcomes to the total outcomes.

There are two B's in the word "PROBABILITY," and there are a total of 11 letters.

She draws the letters without returning it

The probability is given by:

P( drawing B) = Number of ways to draw two B/Total number of outcomes

P(drawing first B) = 2/11

P(drawing 2nd B) = 1/10

P(drawing two B's) = 2/11 * 1/10

= 1/55

So, the probability that Maria draws two B's is 1/55.
