y^2 - 3y - 9

Step-by-step explanation:

Combining Like Terms: y^2 - 3y - 9

Writing in Standard Form: y^2 - 3y - 9

mean, 40.6

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.
