The spinner is expected to have to spin approximately ______ times for a multiple of 3 to be spun 6 times.

Question 8 options:

12


16


24


48

Answer 1

For one spin

• Sample space ={1,2,..,8}

So

• |S|=8

Elements which are multiple of 3

• 3,6

Now

For 6 spins

Total time spins as multiple of 3

• 2(6)=12 times
