Which pair of equations can be used to verify the rectangular form, z = a + bi, and the polar form of a complex number are equivalent? a = sin(θ) and b = cos(θ)
a = cos(θ) and b = sin(θ)
a = rsin(θ) and b = rcos(θ)
a = rcos(θ) and b = rsin(θ)

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.

its very big question plz make it small
