(b) is correct. (a) is not.

(a)

spinner 1 {1,2,3,4} probability of getting an odd number is

spinner 2 {5,6,7,8}probability of getting an odd number is

x= the number of odd numbers

pr(x=1)= [pr(spinner1 has odd number)*pr(spinner2 does not have odd number)]+pr(spinner2 has odd number)*pr(spinner1 does not have odd number)]

pr(x=2)=pr(spinner1 AND spinner2 both have odd numbers)

Therefore,

Oops! I should learn to read. Both are correct!
