"What is the probability that the marble picked will not be green?"
Well, simply all the purple and blue together :)
6 + 4 = 10
So, 10 marbles are not going to be green.
So, 10 green, 10 non-green.
So, our probability is 10 : 10
Which, simplified, is 1 : 1

Answer:
Total derangement = 4
Step-by-step explanation:
To find - How many derangement of {1, 2, 3, 4, 5, 6} begin with the integers 1, 2, and 3, in some order?
Solution -
Given that,
The first three numbers are 1, 2, 3
The only derangement possible are - 231 and 312
Now,
The remaining elements 4, 5, 6 are the 4th, 5th and 6th number in the derangement
Now,
In order for the permutation of the derangement, the only possibility for 123 are 564 and 645
∴ we get
The Total derangement are -
231564
231645
312564
312645
So,
Total derangement = 4
