Six sophomores and 14 freshmen are competing for two alternate positions on the debate team. which expression represents the probability that both students chosen are sophomores?

Step-by-step explanation:

According to the question total sophomores = 6

Total freshmen = 14

Therefore, total persons = 6+ 14 = 20

Thus, If two person are chosen the probability that both are sophomores,

P =  Total combination of 2 person from the group of 6 sophomores/ total persons

P = , which is the required expression.

Note: we can further solve the value of P as follow,

⇒P=

⇒P=

⇒P=

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
