Two unique letters are chosen at random from the alphabet. what is the approximate probability that the first letter chosen is a? a. 0.0385 b. 0.0400 c. 0.0769 d. 0.0800

Answer-

The approximate probability that the first letter chosen is A, is 0.0385 or 3.85%.

Solution-

The total number of ways, two letter can be chosen from alphabets of 26, is

As for the first draw there are 26 letters, and for the second draw there are one less letters, i.e 25

The number of ways letters are chosen such that the first one is A, is

As in the first draw we have only one option, for the second one there can be any letter rather than A (as A is already been drawn)

Probability that the first letter chosen is A, is

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
