You mix the letters S, E, M, I, T, R, O, P, I, C, A, and L thoroughly. Without looking, you draw one letter. Find the probability that you select a vowel. Write your answer as a fraction in simplest form

OpenStudy (anonymous):

A. 12/5 B. 5/12 C. 1/3 D. 7/12

OpenStudy (anonymous):

how many letters are there

OpenStudy (anonymous):

S, E, M, I, T, R, O, P, I, C, A

OpenStudy (anonymous):

good job!

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

can you help me with another question

OpenStudy (anonymous):

Sure

OpenStudy (anonymous):

You roll a standard number cube once. Find P (0).

OpenStudy (anonymous):

Is that all it says?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Oh, ok

OpenStudy (anonymous):

I assume P is supposed to be the number on the die?

OpenStudy (anonymous):

After rolling it, I mean.

OpenStudy (anonymous):

A. 7/6 B. 1 C. 1/2 D. 0

OpenStudy (anonymous):

So, is it the probability of getting 0 on the die?
