An arts and craft supply store has a large crate that contains ​, glass ​, brass and beads. Several friends take turns pushing their hands into the​ beads, grabbing​ one, recording the bead​ type, and placing the bead back into the crate. They then repeat the process. The table shows the count for each bead type. Write a probability model for choosing a bead. Glass: 80
brass: 128
wood: 192

P(glass)=

1/5

Step-by-step explanation:

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
