1. Use the coordinates below to determine if AABC and ADEF are congruent. A(2, -8), B(-5, -2), C(-7,3), D(-9, 7), E(-11, 12), F(-2, 1)

B=

DE =

7.3

step-by-step explanation:

or

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.
