Question

A spinner is numbered from 1 through 10 with each number equally likely to occur. What is the probability of obtaining a number less than 2 or greater than 7 in a single spin?

2/5
1/2
2 1/2
3/10

Answer 1

1, 8, 9 are your favorable outcomes.

The total outcomes are 10.

Answer 2

The probability is simply number of favorable outcomes over total number of outcomes.

Answer 3

so the odds of any 1 number is 1/10

theres only 1 number less than 2.....and there's only 3 numbers greater than 7

so you have 1/10 and 3/10

the chances of have either are 4/10 I believe

Answer 4

1, 8, 9, 10*

Answer 5

so 2/5
