You're having dinner at a restaurant that serves
5
kinds of pasta (spaghetti, bow ties, fettuccine, ravioli, and macaroni) in
4
different flavors (tomato sauce, cheese sauce, meat sauce, and olive oil).
if you randomly pick your kind of pasta and flavor, what is the probability that you'll end up with bow ties, cheese sauce, or both?

Bow ties: 1/5

Cheese sauce: 1/4

Bow ties with cheese sauce: 1/20

Step-by-step explanation:

There are 3 different questions here.

First, you have the pasta question.  What is the probability you'll end up with bow ties?  Well, there are 5 kinds of pasta, all with the same chance to be chosen... so you have 1 chance out of 5 to pick bow ties.

Then the sauce.  Same logic... 4 different sauces...  so 1/4 chance to get the cheese sauce.

For the bow ties and cheese sauce combo, it's a bit different, we're talking about compound probabilities here.

So, you have to multiply the probability  to get bow ties with the probability to get cheese sauce, so:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
