Respuesta :

Answer:

[tex]p = \frac{13}{20}[/tex]

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem:

20 numbers

Multiple of 3:

3,6,9,12,15,18

Greater than 10:

11,12,13,14,15,16,17,18,19,20

Multiple of 3 or greater than 10:

3,6,9, 11,12,13,14,15,16,17,18,19,20

So 13 desired outcomes:

Probability:

[tex]p = \frac{13}{20}[/tex]
