Hello!

First you have to find the probability of picking the right numbers

To do this you do the amount of favorable outcomes over the total amount of outcomes

There are 5 favorable numbers and 18 in total

This is a probability of 5/18

For the second number there of 4 favorable numbers and 17 in total since you already picked one

This is a probability of 4/ 17

For the third number there are 3 favorable numbers and 16 in total

This is a probability of 3/ 16

For the fourth number there are 2 favorable numbers and 15 in total

This is a probability of 2/ 15

For the fifth number there are 1 favorable numbers and 14 in total

This is a probability of 1/14

To get the answer you multiply all the probabilities together

5/18 * 4/17 * 3/16 * 2/15 * 1/14 = 1 / 8568

The answer is \frac{1}{8568}

Hope this helps!

A triangle has sides with lengths of 60 centimeters, 63 centimeters, and 87 centimeters. Is it a right triangle
lozanna [386]
We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:
60^2+63^2 = 87^2
7569 = 7569

This is, indeed correct, thus, this <em>is </em><em>a right triangle.</em>
