Question 971025: There is a spinner labeled with the numbers 1, 2, 3, 4, 8, 9, 10, and 12. What is the probability to spin a number less than 4 and odd? What is the probability to spin a number greater than 6 or even? (I'm pretty sure the first question is 2/8, but please explain the or question)

8 possible outcomes
Less than 4 and odd : 2 possible outcomes (1,3)
So,
P=2%2F8=1%2F4
.
.
.
Greater than 6 : 4 possible outcomes (8,9,10,12)
Even : 5 possible outcomes (2,4,8,10,12)
Greater than 6 and even : 3 possible outcomes (8,10,12)<--- Eliminates double counting
So,
P=%284%2B5-3%29%2F8=6%2F8=3%2F4
