It is the third option: (10C1) (20C1( / 50C2.
Step-by-step explanation:
The number of ways of selecting 2 marbles = the number of combination of any 2 marbles in the 50 marbles in the bag and this is 50C2. It is combinations because the order of drawing the marbles does not matter.
The number of combinations of one being red and the other blue = 10C1 times 20C1.
So the answer is (10C1) (20C1( / 50C2.
Hello!
when taking a number and finding 95% of it, you would usually take the number and multiply it by .95
To find the original number, reverse this process like so:
42.75/.95=45
<u><em>95% of 45 is 42.75</em></u>
I hope this helps, and have a nice day!
