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

Answer 1

Answer: 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%

Answer 2

Answer:

i think thats a 1 in 20th chance

that's an equilateral triangle which means that all sides and angles are equal to each other. So now if you set everything equal to each other you get 2(2x+1)=6x+7y. Now it's just algebra after that, you have to distribute then left side then isolate the variable y and you get a y value. next step is pretty simple just substitute the answer that you got for y into the original equation that included y so you can get an x value. if everything is right it should tell you that the final answer is 14.
