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

Answer:

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

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=(1* 2)/(5)


P=(2)/(5)


P=0.4

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