In how many ways can a group of 5 men and 2 women be made out of a total of 7 men and 3 women?
A. 64
В. 1 1
C. 126
D. 63

D 63

Explanation:

Required number of ways = (7C5*3C2) = (7C2*3C1) = 63

the answer should be a. snail

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
