Question

A number card numbered from 1 to 30

is drawn randomly.
What is the
probability of getting
a card having
the number divisible by 6 or 7?​

Answer 1

3/10

Explanation:

We have to list out the numbers that are divisible by 6 and 7 that we can find between 1 and 30

so, we have this as;

6,7,12,14,18, 21, 24,28 and 30

The count we have here is 9

The total number we have is 30

So the probability is simply the count we have divided by 30

so we have this as ; 9/30 =

3/10
