Lucinda is trying to show her brother a new magic trick with a deck of cards. If she asks her brother to draw a card from the deck. What is the probability that he will draw an ace? A. 1/52
B. 1/50
C. 1/13
D. 1/4

c

Step-by-step explanation:

4 aces in 1 deck of 52 cards 52/4 = 13, 4/4 = 1

which means 1/13

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
