Find each probability separately and then multiply the two together
Probability for even number is 3/6 or 1/2 because their are 3 even numbers out of 6 numbers
Probability to get a black chip is 1 black chip out of 3 totals so 1/3
Multiply 1/3 by 1/2
Answer 1/6
Compab=a.b/|a|
b=<0,1,−2√10>
a.b= 2√10
|a| = √10
a.b/|a|=2√10 / √10=2
I'm assuming this is multiple choice and you forgot to post the answers. I'll take a guess and say it probably looks something like this:

Because you can't take the square root of a negative number without getting an imaginary result, resulting in the function having a closed domain limit.
Where is the table..? You didn't provide any pictures..
