Will give

1. give an example of an event that is certain and an event that is impossible. what are the probabilities for each event?

2. thomas rolled a six sided die 100 times. he recorded his results as odd or even. the number of odds were 42 and the number of evens were 58. he thought he would get 50 heads and 50 tails. explain to thomas why the experimental probability may be different from the theoretical probability.

Step-by-step explanation:

1. An event that is certain is something that will definitely happen, such as the sun will rise tomorrow, or when rolling a six sided die, it will land on 1 - 6.

Something impossible, includes events that will never happen, such as pig will fly, or when rolling a six sided die, it will land on 7.

2. The experimental probability may be different to the theoretical probability as theoretical probability is only theory, and when trying something out in real life, there is a high chance that it will be different.

the aswere is the one with all 8's and the second one is with the 10,8 and 6

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
