The company uses the program to make a code, one character at a time.

What is the probability the first character is a symbol?

Enter your answer as a decimal rounded to the nearest hundredth in the box.

Answer 1

Answer:

The probability that the first character is a symbol is 0.13.

Step-by-step explanation:

Given is :

There are 4 symbols and 26 alphabets.

The codes are made up from the symbols !, #, &, and *, as well as any letter from the alphabet.

So, in total the code is a 5 digit code with 4 symbols and one alphabet.

Total possible outcomes are 4+26 = 30 and out of this 4 are symbols.

Now, the probability the first character is a symbol will be ::

$\frac{4}{30} =0.13$

Answer 2

So there are 26 letters in the alphabet and 4 symbols here. If you calculate 4 out of 26, that would equal 15.38% or 0.15.
