Work in reverse.

45 + 15= 60. 60/2= 30. 30 + x = 47.

So, x= 47-30.
x= 17.

How many of these integers are not divisible by 5 or 6?
dimaraw [331]

This is an EXAMPLE on how to do this..

The above code shows the following answers: 6,7,12,14,18,21,24,28,30,35,36,42,48,49,54,56,60,63,66,70,72,77,78,84,90,91,96,98

Now the bold numbers 42 and 84 are both divisbile by 6 and 7. Now If I change the || to && in the above code, the result shows only 42 and 84.

What change should I do to remove these 2 numbers from the final result?

Answer:

  • 15

Step-by-step explanation:

<u>There are total cadies in the bag:</u>

  • 7 + 13 + 5 = 25

<u>Probability of pulling a coffee candy is:</u>

  • 5/25 = 1/5

So each 5th candy should be coffee candy

<u>Then you need to pull at least:</u>

  • 5*3 = 15 candies

<em><u>Note:</u></em>

<em><u>To ensure 3 coffee candies you would need to pull 25 - 2 = 23 candies</u></em>
