A number from the list {2, 4, 5, 7, 9, 10, 12, 15, 18, 20} is to be picked at random. What is the probability of getting an even number? Write your answer in the simplest form of fraction. and be right
There are a total of 10 numbers in the list and 5 even numbers (2, 4, 10, 12, 18).
Therefore, the probability of getting an even number is 5/10 = 1/2.
stop saying 1/2 cus its wrong
I apologize for the mistake in my previous response. Let's correct it:
There are a total of 10 numbers in the list, and 5 of them are even numbers (2, 4, 10, 12, 18).
The probability of getting an even number is:
Number of favorable outcomes (even numbers) / Total number of outcomes
= 5/10
= 1/2
So, the correct answer is 1/2.
its not 1/2
I apologize for the confusion earlier. Let's correct the calculation:
Number of even numbers = 5 (2, 4, 10, 12, 18)
Total numbers = 10 (2, 4, 5, 7, 9, 10, 12, 15, 18, 20)
Probability of getting an even number = Number of even numbers / Total numbers
Probability = 5/10 = 1/2
Therefore, the correct probability of picking an even number from the list is 1/2.
