From a group of 8 people, including george and nina, 3 people are to be selected at random to work on a certain project. what is the probability that the 3 people selected will include george but not nina?

Step-by-step explanation:

We have to select george but not nina with two other people

No. of ways  selecting 2 two people knowing Geroge will be the third one is

(beacuse we have to exclude Nina)

And total no of ways of selecting 3 people out of 8 people is

Therefore the required Probability is    

=

idk

step-by-step explanation: i just don't

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
