Four seniors and six juniors are competing for four places on a quiz bowl team.

what is the approximate probability that all four seniors will be chosen at random?

0.00020
0.00476
0.06667
0.07142

The correct answer is:

B. 0.00476

The approximate probability that all four seniors will be chosen at random is 0.00476.

2+2 = 4 2+1+1=4

Step-by-step explanation:

Systems of equations that have the same solution are called equivalent systems. Given a system of two equations, we can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself.
