Answer:

in a region with a letter

Step-by-step explanation:

For a certainty, then probability is 1.

That means sum of probability of all events in the sample space.

This means P(A)+P(B)+P(C)+P(D)=1

This is equivalent to:

P(A or B or C or D)=1

Hence for certainty, the region must be:

A or B or C or D

So the correct answer is in a region with a letter.

4% is not equivalent to 40%
0.4 is equivalent to 40%. Just move the decimal two places to the right.
2/5 is equivalent to 0.4, which in turn is equivalent to 40%. 2 divided by 5=0.4

Alladin went grocery shopping for candy at Costco in Rego Park. He wants to buy the package of candy with the greatest percentag

Pavlova-9 [17]

We need to find what percentage represents the number of Hershey's Cookie Crème Candy Bars in each package, and then compare which one is better.

For package A.

It has 13 Hershey's Cookie Crème Candy Bars out of 25. To find which percentage is 13 out of 25 we do the following:

• Divide 100 by the total amount of candy 25, and multiply the result by 13:

$\frac{100}{25}\times13$

we get the following percentage:

$\frac{100}{25}\times13=4\times13=52$

Package A has 52% of Hershey's Cookie Crème Candy Bars.

For package B.

It has 11 Hershey's Cookie Crème Candy Bars out of 20. we do the same as before to find the percentage, only that this time, instead of dividing by 25, we divide 100 by 20, and intead of multiplying by 12, we multiply by 11:

$\frac{100}{20}\times11$

The result is:

$\frac{100}{20}\times11=5\times11=55$

Package B has 55% of Hershey's Cookie Crème Candy Bars.

Which package should Alladin buy? He should buy Package B because it has a greater percentage.
