Cards numbered 1 through 30 are placed in a bag and shuffled. One card is chosen at random. What is the probability of randomly selecting a number less than or equal to 5, or a multiple of 7? A. 1/30 B. 2/15 C. 1/15 D. 3/10

Vocaloid (vocaloid):

weird, none of the answers match what I think it is numbers less than/equal to 5: 1,2,3,4,5 multiples of 7: 7,21,28 so, 8 numbers out of 30, but that's not one of the choices

OpenStudy (anonimous):

Maybe 1/30?

OpenStudy (anonimous):

or simplify it

Vocaloid (vocaloid):

8/30 is 4/15 which isn't one of the choices

Vocaloid (vocaloid):

oh wait

Vocaloid (vocaloid):

i missed one

Vocaloid (vocaloid):

multiples of 7: 7,14,21,28

Vocaloid (vocaloid):

so 9 numbers out of 30

Vocaloid (vocaloid):

which simplifies to....?

OpenStudy (anonimous):

3/10?

Vocaloid (vocaloid):

great!
