You want to make five-letter codes that use the letters A, F, E, R, and M without repeating any letter. What is the probability that a randomly chosen code starts
with A?

0.10

0.15

0.20

0.25

Respuesta :

Any of the given 5 letters can be at the start of the code. 
Total choices = 5

We want the code to start with A
Choices in favor = 1

Probability = favorable/total = 1/5 = 0.20

Answer:

(C)0.20

Step-by-step explanation:

We are given that we have to make five-letter codes that use the letters A, F, E, R, and M without repeating any letter.

Thus, total number of letters=5

Now, the probability that a randomly chosen code starts with A is given as:

[tex]P=\frac{Favourable outcomes}{Total number of outcomes}[/tex]

[tex]P=\frac{1}{5}[/tex]

[tex]P=0.20[/tex]

Therefore, the the probability that a randomly chosen code starts with A is 0.20.

Hence, option C is correct.
