A number is chosen at random from 1 to 25. Find the probability of selecting an even number or multiple of 13
1 answer:
Probability helps us to know the chances of an event occurring. The probability of selecting an even number or multiple of 13 is 13/25.
<h3>What is Probability?</h3>Probability helps us to know the chances of an event occurring.
Number of even numbers between 1 to 25 = 22
Number of multiple of 13 between 1 to 25 = 1
The probability of selecting an even number or multiple of 13 is,
Probability = (12+1)/25 = 13/25
Hence, The probability of selecting an even number or multiple of 13 is 13/25.

Question:
Below are 36 sorted ages of an acting award winner. find the percentile corresponding to age 38 using the method presented in the textbook. 18 19 20 20 21 23 25 31 33 34 35 37 38 47 50 51 55 55 58 59 62 62 64 66 69 70 70 70 71 71 72 74 74 75 77 80 percentile of value 38 = ______ (round to the nearest integer as needed.)
Answer:
33 percentile
Step-by-step explanation:
Given the ages:
18, 19, 20, 20, 21, 23, 25, 31, 33, 34, 35, 37, 38, 47, 50, 51, 55, 55, 58, 59, 62, 62, 64, 66, 69, 70, 70, 70, 71, 71, 72, 74, 74, 75, 77, 80.
We are told to find the percentile corresponding to age 38.
To find the percentile corresponding to age 38 simply means to find the percentage of ages that are less than 38.
From the given values, the number of ages less than 38 are 12. Therefore, the percentile corresponding to age 38 would be:
(Ages less than 38/ total number of ages) * 100
33.333 ≈ 33
The percentile corresponding to age 38 = 33 percentile
