oee [108]
First, we need to figure out 10% of fifteen.

So, we multiple 15 by 10% (or 0.1 in simpler terms).

That gives us 1.5, which is our mark-up price.

So, finally we add the markup price to the original price to obtain the selling price.

1.5 + 15 = 16.5

The owner charges $16.50 for 1kg of sugar!

6)The experimental probability is 39%.(39/100(100)).

7) The theoretical probability is theoretical. This is when something should happen without taking external forces into account. Experimental probability is taking the external forces into account which is why the probability is not as clean cut.

The theoretical probability should be 33%.
The experimental probability is actually 39%.
