Question

A computer randomly picks a number from the group 75, 76, 77, 78, 79 What is the probability the number selected is larger than 78 or even?
Enter your answer in the box as a decimal.

Answer 1

Since there are only 2 numbers in the sequence that are even or greater than 78 it's 2/5th or 0.4

Answer 2

Answer:

The probability the number selected is larger than 78 or even is 0.4.

Step-by-step explanation:

Given : A computer randomly picks a number from the group 75, 76, 77, 78, 79.

To find : What is the probability the number selected is larger than 78 or even?

Solution :

Data - 75, 76, 77, 78, 79

The number selected is larger than 78 i.e. 79=1

The number selected is even i.e.  76,78 =2

The number selected is larger than 78 or even is 1×2.

Total number of outcome = 5

The probability the number selected is larger than 78 or even is

$P=\frac{1\times 2}{5}$

$P=\frac{2}{5}$

$P=0.4$

Therefore, The probability the number selected is larger than 78 or even is 0.4.
