Numbers 1 - 10 are written on cards and placed in a bag. Find the probability of choosing a number greater than 5 or choosing an odd number. I got 2/5 but im not sure it's correct

OpenStudy (anonymous):

1,3,5,6,7,8,9 those are the possibilities

OpenStudy (anonymous):

Alright

OpenStudy (mathstudent55):

\(P(\text{event}) = \dfrac{\text{number of desired outcomes}}{\text{total number of possible outcomes}} \) When you pick one card, there are 10 possible outcomes. How many numbers are greater than 5? How many numbers are odd? How many of the odd numbers are not already included in the numbers greater than 5?

OpenStudy (anonymous):

so they are out of 10 and there are 8 possibilities making it.....

OpenStudy (anonymous):

So is it 2/5?

OpenStudy (anonymous):

no how did you get that?

OpenStudy (anonymous):
