Question

You spin 2 spinners. spinner A has the options red, green, and blue. All the sections on the spinner are equal. Spinner B has the options 1,2,3. all the sections are equal. what is the probability of:

spinning green and an odd number?
1/3, 1/6, 1/9, or 2/4?
spinning blue and a 2?
1/6, 1/9, 5/9 2/9?
please help me soon thanks!

Answer 1

Part A:
`(2)/(9) \\`

Part B:
`(1)/(9)`

Explanation:

Calculate compound independent probabilities by multiplying the probability of each together.

Part A

Probability of landing green: 1/3

Probability of an odd number: 2/3

Probability of green and odd:
`(1)/(3) *(2)/(3) = (2)/(9)`

Check work: Only two possibilities with green and odd condition are green+1 and green+3.

Part B

Probability of landing blue: 1/3

Probability of landing 2: 1/3

Probability of blue and 2:
`(1)/(3) * (1)/(3) = (1)/(9)`

Check work: Only possibility with blue and 2 are just that: Blue + 2
