Suppose a-b=0a−b=0a, minus, b, equals, 0 and a, b\ne0a, b≠0a, comma, b, does not equal, 0. which one of these expressions equals \dfrac{b}{a} a b start fraction, b, divided by, a, end fraction ?

it is given that

a-b=0

Adding , b to both sides

→a-b+b=0+b

→a=b

Dividing both sides by , b we get

So,Among the expression given above, which is equivalent to

Option 1: a-b=0

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.
