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.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

1/800 is the right answer
