-3(3f+4s=523)+(9f+3s=507)

-9f-12s+9f+3s=-1569+507

-9s=-1062

s=118,  making 3f+4s=523 become:

3f+472=523

3f=51

f=17

So the reels are $17 each and the rods are $118 each.

A die is rolled twice. What is the probability of showing a 1 on the first roll and an even number on the second roll?
Ivan

Answer:

1/12

Step-by-step explanation:

Okay, so this will be a compound probability question because there are two parts to the question.

Firstly, a die has 6 sides, and there is only one chance of getting a 1, so the probability would be 1/6.

Furthermore, there are 3 different even numbers on a 6-sided die, so that is 3/6, which can be simplified to 1/2.

Now, because this is a compound probability, we have to multiply 1/2 and 1/6 together, which would give us our answer of 1/12.
