Question

you have a bag of 5 marbles a red green blue yellow and white one. find the probability that you pick the blue one then the yellow one( you don't replace the first Marvel you draw). express your answer as a simplified fraction ​

Answer 1

1/20

Explanation:

Simple probability problems are the best because the method is easily applicable to everything else!

There are 5 total marbles and 1 of each color.

So the first draw has a 1 / 5 probability of being blue.

The second draw has a 1 / 4 probability of being yellow (there are only 4 remaining marbles in the bag after you take the blue out permanently)

Then, you multiply these together, and get:

1/20!

Good luck!
