Solve by Substitution :

// Solve equation [2] for the variable  y

// Plug this in for variable  y  in equation [1]

/ Solve equation [1] for the variable  x

// By now we know this much :

// Use the  x  value to solve for  y

Solution :

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.
