Answer:

  • 2/3 or 66.66%

Step-by-step explanation:

Out of 30 numbers, half is multiple of 2 and the third is multiple of 3.

We have 15 even numbers and 10 multiples of 3. Out of 10, half is even numbers and  therefore counted twice.

So we subtract 5 to get:

  • 15 + 10 - 5 = 20 numbers

If we chose one ticket at random the probability is:

  • P(2x or 3x) = 20/30 = 2/3 or 66.66%
