If a letter is chosen at random from the word mathematics, what is the probability of choosing a t? a. 1/11 b. 2/11 c. 4/11 d. 5/11

option B. 2/11

Explanation:

1)
                       number of positive outcomes
Probability =
                        number of possible outcomes

2) Number of positive outcomes:

The positive outcome is choosing a T, given that there are two Ts, the number of positive outcomes is 2.

3) Number of possible outcomes

There are 11 letters, so the number of total outcomes is 11.

4) Therefore,

                        2
probability = 
                       11
