Question

A number is chosen at random from the set {4, 7, 10, 13, 16}. What is the probability that the number is:

a. Even
b. Odd
c. Greater than 10
d. Less than 10
e. Between 4 and 19.

Answer 1

The probabilities for selecting different kinds of numbers from the given set {4, 7, 10, 13, 16} can be calculated.

Step-by-step explanation:

a. There are 3 even numbers in the set {4, 7, 10, 13, 16}, which means that the probability of randomly choosing an even number is 3/5.

b. There are 2 odd numbers in the set {4, 7, 10, 13, 16}, which means that the probability of randomly choosing an odd number is 2/5.

c. There are 2 numbers greater than 10 in the set {4, 7, 10, 13, 16}, which means that the probability of randomly choosing a number greater than 10 is 2/5.

d. There are 3 numbers less than 10 in the set {4, 7, 10, 13, 16}, which means that the probability of randomly choosing a number less than 10 is 3/5.

e. There are 5 numbers between 4 and 19 in the set {4, 7, 10, 13, 16}, which means that the probability of randomly choosing a number between 4 and 19 is 5/5 or 1.
