How about this:
The book has 712 pages. Ted has already read 408 pages, so he has 304 left to read.
712 - 408 = 304
The probability to choose letter n is
. After drawing letter n there left 25 letters and the probability to choose the letter w is
. After drawing two letters n and w there left 24 letters and then the probability to choose letter b is
. After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is
.
Using the product rule for probabilities, you can obtain that
.
Answer:
Step-by-step explanation:

There’s a 3:1:2 ratio. If you add those numbers up you get 6.
Divide 36 by 6 to get 6.
Now multiply the numbers in the ratio by 6 and you should get....
18 : 6 : 12
Notice how if you add those up you get 36
So: there are 18 silver beads, 6 crystal and 12 purple
Hope this helps! Any questions let me know :)
What I would do first us do 56 times 20. Then do 56 times 7. Add those two together.
