A student is asked to make up a 6 digit number by arranging the digits 111223. What is the probability that he will pick a number that has the 2's separated?

Math (Grade 12 Data Management)  Reiny, Wednesday, November 28, 2007 at 4:30pm
Total number of arrangements = 6!/(3!2!)
= 60
No of ways where the 2's are together
= 5!/3!
= 20
so the number of ways the 2's are apart
= 40
so the Prob(the 2's are separated) = 40/60
= 2/3

Does interchanging the independant and dependant variables change the correlation coefficient for the set of data

No it does not change the correlation and coeddicient for the set of data because they are meant to correspond from one another.

There are two dice. one red and the other white. How many outcomes are possible

If they're standard dice that means they have 6 sides.
You have 2 dice so that's 12 sides
12! = 479'001'600
Correct me if I'm wrong
