1/13 is the probability of choosing a letter from the word MATH then getting tails.
<u>Step-by-step explanation:</u>
A letter of the alphabet is chosen at a random.
The total number of alphabets = 26 letters.
Then a coin is flipped.
The total number of outcomes when a coin is flipped ⇒ Head, Tail = 2.
Now, we need to find the probability of choosing a letter from the word MATH and then getting tails.
<u>Probability of choosing a letter from the word MATH :</u>
P(a letter) = No.of letters in MATH / total number of alphabets.
⇒ 4/26
<u>Probability of getting a tail when a coin is flipped :</u>
P(a tail) = No.of tails / total outcomes.
⇒ 1/2
<u>Probability of choosing a letter from the word MATH then getting tails :</u>
⇒ 4/26 × 1/2
⇒ 4/52
⇒ 1/13
∴ The probability of choosing a letter from the word MATH then getting tails is 1/13.
