Answer:
The probability that the HR director will select an employee who is not a multiple of 13 is
Step-by-step explanation:
* <em>Lets explain how to solve the problem</em>
- The probability of an event is the measure of the chance that the
event will occur
- The probability of an event A is the number of ways that event A can
occur divided by the total number of possible outcomes
- If P(A) is the probability of event A, is the probability that the event A
does not occur is 1 - P(A)
* <em>Lets solve the problem</em>
- An HR director numbered employees 1 through 50 for an extra
vacation day contest
∴ There are 50 employees
- The HR director will select an employee
- We need to find the probability of select an employees who is not
multiple of 13
* At first lets find the multiples of 13
∵ 13 × 1 = 13
∵ 13 × 2 = 26
∵ 13 × 3 = 39
∴ The multiples of 13 from 1 to 50 are 13 , 26 , 39
∵ There are 3 multiples of 13
∵ There are 50 numbers
∵ Probability of multiple of 13 =
∵ Probability of not multiple of 13 = 1 - P(multiple of 13)
∴ Probability of not multiple of 13 =
∴ Probability of not multiple of 13 =
* The probability that the HR director will select an employee who is
not a multiple of 13 is
I will say there are two ways to solve this problem. The first is, you can use your calculator and calculate it to see which is the closest to 2. The second way is divide it and here is how you do it:
1 is just 1
15/16 = 16 goes into 15 for less than one
17/8 = 8 goes into 17 for more than two so you can rewrite it as
63/33 = 33 does not go into 63 for two
So the answer is 17/8
1 is just 1
15/16 = 16 goes into 15 for less than one
17/8 = 8 goes into 17 for more than two so you can rewrite it as
63/33 = 33 does not go into 63 for two
So the answer is 17/8
