. Suppose that 10 students of a class of 50 undergraduates are chosen for a behavioral experiment. The total class consists of 1

Natali [406]

Answer:

Approximately 0% probability of the group contains exactly seven seniors and three juniors.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order in which the students are chosen is not important, which means that we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Desired outcomes:

7 seniors, from a set of 7.

3 juniors, from a set of 10. So

$D = C_{7,7} \times C_{10,3} = \frac{7!}{7!(7-7)!} \times \frac{10!}{3!(10-3)&} = 1 \times 120 = 120$

Total outcomes:

10 students froms a set of 50. so

$T = C_{50,10} = \frac{50!}{10!(50-10)!} = 10272278170$

Probability:

$p = \frac{D}{T} = \frac{120}{10272278170} \approx 0$

Approximately 0% probability of the group contains exactly seven seniors and three juniors.

I'm going to assume that they are on parallel tracks, and not the same track.

60x=40(x+2)

60x=40x+80

20x=80

x=4

You can check the work I've provided by filling in the answer for x into the initial question.
