Add the following 3l²mn-lm²n+2lm²n+lmn²+-3lmn²+2l²mn< br />pls don't spam​

5l²mn + lm²n - 2lmn².

Step-by-step explanation:

3l²mn - lm²n + 2lm²n + lmn² + -3lmn² +2l²mn

Bringing like terms together:

= 3l²mn +2l²mn  - lm²n + 2lm²n + lmn² - 3lmn²

= 5l²mn + lm²n - 2lmn².

question is incomplete.

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.
