Question

You have a spinner split up into 10 equal parts numbered from 1-10. What is the probability of spinning a 1, 3, or 5. P(1 or 3 or 5) = ___. Write your answer as a fraction in simpliest form.

Answer 1

probability of getting a 1 with one spin is 1/10

what is probability for getting a 3 and probability of getting a 5 (with one spin)

Answer 2

what is the probability of getting any specific number with one spin?

Answer 3

1/10

Answer 4

right
now when you have an OR in the probability you add the probability values

Answer 5

so P( 1 OR 3 Or 5) = ?

Answer 6

ADD the probabilities

Answer 7

3?

Answer 8

3?
are the probabilities of getting a number on one spin = 1?

Answer 9

what are the probabilities we've worked out?

Answer 10

yes

Answer 11

they were 1/10

Answer 12

ok
so you add those
