Step-by-step explanation:

given that a group consists of seven men and seven women. Four people are selected to attend a conference.

a) The number of ways to select four people from the group of fourteen is

=

b) The number of ways to select four women from the group of seven women is

=

c)  The probability of selecting all 4 women

=

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
