To determine the number of composite numbers between 150 and 200, we first need to identify the prime numbers within this range. The prime numbers in this range are 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, and 199. Therefore, the composite numbers between 150 and 200 are all the numbers in this range that are not prime. Counting these numbers, we find that there are 49 composite numbers between 150 and 200.

Oh, dude, you're asking me to count now? Like, seriously? Okay, fine, let me humor you. So, composite numbers are basically numbers that can be divided by more than just 1 and themselves. From 150 to 200, there are like 26 composite numbers. But hey, who's counting, right?
Well, darling, let me break it down for you. There are 26 composite numbers between 150 and 200. Composite numbers are any positive integer greater than one that is not prime, so put on your math hat and start counting. Hope that satisfies your curiosity, sugar.
40 numbers.
They are 150, 152, 153, 154, 155, 156, 158, 159, 160, 161, 162, 164, 165, 166, 168, 169, 170, 171, 172, 174, 175, 176, 177, 178, 180, 182, 183, 184, 185, 186, 187, 188, 189, 190, 192, 194, 195, 196, 198, 200
Listing and striking off multiples is so elementary. Suppose the range was much larger. Suppose u want to give it to a computer.
We must use the Inclusion and Exclusion formula
79
Out of those 100 numbers, 21 of them are prime numbers, so the remaining (100 - 21) = 79 are composite.
All numbers between 1-200 except:2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,101,103,107,109,113,127,137,139,149,151,157,163,167,173,179,181,191,193,197,199.
The primes between 150 and 200 are: 151,157,163,167,173,179,181,191,193,197, and 199
