Example 4.11 A fair dice is rolled once. Find the probability of getting
(a) an even number,
(b) a number less than 5,
(c) a number that can be divided by 2,
(d) a number that cannot be divided by 2,
(e) an even number or a number less than 5.

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

yes because they have the same amount of green and blur marbles.
