There are 8 red, 5 yellow and 7 green cubes in a box. What is the probability of drawing a yellow cube and then a green cube, if the first cube is not replaced before the second cube is drawn?
Answers
Step 1: find out how many cubes are there in total. There are 20 cubes total because 8+5+7 = 20
Step 2: find out how many yellow cubes you have. In this problem you have 5 yellow cubes out of 20 cubes. So you chances of grabbing a yellow cube is 5 out of 20.
Step 3: simplify. You can simplify 5/20 to 1/5. So you have a 1/5 chance of grabbing a yellow cube.
Step 4: now find how many cube are green. You have 7 green cubes. Because you took out one cube and didn't replace it you now have 19 cubes. So you have a 7/19 chance of grabbing a green cube.
Step 5: now multiply 7/19 times 1/5. Please note you can not simplify 7/19 because 7 and 19 are prime numbers.
Answer 7/95 which is roughly around .073 or 7.3%
i think thats a 1 in 20th chance

One number is 1 more than 4 times another. Their product is 18. What are the numbers?
Answers
The numbers are 9 and 2.
One number is 1 more than 4 times another. 2 x 4 = 8 8 + 1 = 9
Their product is 18. 9 x 2 = 18
Usually, with this type of problem, it's easiest just to use trial and error. Go through the factors of 18, and eventually you'll find a pair that fits the given criteria.
