If there are 13 letters typed, the probability that no letters will be repeated can be found to be 1.05 x 10⁻²⁰
<h3>How to find the probability no letters are repeated?</h3>
First, find the number of possibilities of 13 letters from 26 letters in the alphabet as:
= 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26
= 6.156 x 10³⁶ possibilities
If the numbers are not to be repeated then the possibilities are:
= 26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 16 x 15 x 14
= 64764752532480000 possibilities
The probability that no letters are repeated is:
= 64764752532480000 / 6.156 x 10³⁶
= 0.0000000000000000000105
= 1.05 x 10⁻²⁰

Answer:
13.03
Step-by-step explanation:
7 x 7 = 49
11 x 11 = 121
121 + 49 = 170
The square root of 170 is 13.03
Hope this helped!
(And maybe give me brainliest?)
Have a great day!
The answer is going to be C because you cannot take the square root of 3 and 13. Which means you cannot simplify the square root of 39 any further
Answer:
choose the first
Step-by-step explanation:
When h=0, T is the highest (because the temperature is highest at noon)
And knowing that the temperature difference in the world cannot exceed 60 degrees in a day, only the first choice is common sense.
