There are 42 citizens called for jury duty. Eleven are randomly chosen to for the interview phase. How many different ways can t
Sunny_sXe [5.5K]

The quick way to get the answer is just type "42 choose 11" into Google.

Or if you want to figure it out yourself, you have 42 choices for the first potential juror, 41 choices for the second potential juror, etc.

Now before you stop there, you only care about the combination of the 11 people chosen, not what order they are selected, so you need to divide by the ways to arrange 11 people.

Final expression:

C(42,11) = (42 * 41 * 40 * 39 * 38 * 37 * 36 * 35 * 34 * 33 * 32) / (11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1)

Write an expression for the calculation add 3 and 8 and then multiply by 9
melisa1 [442]

Hey there!

Basically it wants you to add 3 and 8 from each other, what ever the answer to that part, you multiply the result by 9

Here this is what i meant

3 + 8 = 11 \\ 11 ( 9) = 99

Or you could do this method too!

(3 +8) (9) \\ \\ 3 + 8 = 11 \\ 11(9) \\ = 99

They both give you the result of 99

So, I am assuming your expression would look like this: (3 + 8) * 9

Good luck on your assignment and enjoy your day!
