A box contains 20 oranges and 10 grapes what is the probability of picking a grape from the box?

Step-by-step explanation:

First, let's find how many total items there are in the box.

If there are 20 oranges and 10 grapes, then there are items in the box.

Now, if there are 10 grapes in this box, we know that the probability of picking a grape is because the total is the denominator and the number of items for that selection is the numerator.

We can simplify this fraction down to .

Hope this helped!

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
