If u = {all positive integers) and a = {x|x eu and x is an odd positive integer}, which describes ac? aº = {xlx eu and is a negative integer} ac = {x|x eu and is zero} aº = {x|x eu and is not an integer} aº = {xlx eu and is an even positive integer}

last choice

Step-by-step explanation:

If we are looking at positive integers and we take out the odd ones, the only one's that are left are the even ones.

So last choice.   (Also I assume AC meant the complement of A)

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
