Answer:
80% probability of not choosing a multiple of five
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes:
In this problem, we have that:
There are 40 numbers between 1 and 40.
Multiples of 5 are: 5,10,15,20,25,30,35,40
So there are 8 numbers that are multiple of 4 and 40-32 = 8 which are not multiples of five.
So
32/40 = 0.8
80% probability of not choosing a multiple of five
Answer: the probability of not choosing a multiple of five is 0.8
Step-by-step explanation:
Probability is expressed as the ratio of the number of favorable outcomes to the total number of outcomes.
In this scenario, the total number of outcomes is 40. The multiple of 5 between 1 to 40 are 5, 10, 15, 20, 25, 30, 35, 40. The total numbers that are multiples of 5 is 8. The total numbers that are not multiples of 5 is 40 - 8 = 32
Therefore, the number of favorable outcomes is 32
Probability = 32/40 = 0.8
