The spinner is divided into equal parts. Use a tree diagram to find the probability that the spinner will land on a consonant the first time and a vowel the second time if the spinner is spun twice

My spinner has 3 parts, N E and U

A:2/3
B:2/9
C:3/4
D:5/9

I think the answer is A. thank you

Your question says that the spinner is divided into four equal parts.
Then you say "My spinner has 3 parts"

So which is it ?

my question said my spinner has equal parts not four equal parts. it is 3.

thank you

You are right!

I can't draw a tree diagram on here, but I can show the math.

Prob(consonant on first spin)
= 1/3

Prob(vowel on 2nd spin)
= 2/3

prob(event as stated)
= (1/3)(2/3)
= 2/9
