two unique letters are chosen at random from the alphabet. what is the approximate probability that the first letter chosen is a?\n0.0385\n0.0400\n0.0769\n0.0800

Answer

Explanation:

Step1: Determine total number of letters

There are 26 letters in the alphabet.

Step2: Calculate probability

The probability of choosing the letter 'A' as the first - letter out of 26 unique letters is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. The number of favorable outcomes (choosing 'A') is 1, and the total number of outcomes is 26. So $P = \frac{1}{26}\approx0.0385$.

Answer:

0.0385
