Answer:

  • 15

Step-by-step explanation:

There are total cadies in the bag:

  • 7 + 13 + 5 = 25

Probability of pulling a coffee candy is:

  • 5/25 = 1/5

So each 5th candy should be coffee candy

Then you need to pull at least:

  • 5*3 = 15 candies

Note:

To ensure 3 coffee candies you would need to pull 25 - 2 = 23 candies
