Simon is doing a card trick using a standard 52 card deck. he shows his friend a card, replace it, and then shows his other friend another card. what is the probability that the first card is not a club and the second card is a diamond?

a. 5/8
b. 1/8
c. 1/2
d. 3/16

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
