Answer:
15/16 cm
Step-by-step explanation:
The drill must go 3/8 of the way from one side of the sheet to the other. The depth that this drill must reach is found by multiplying 2.5 cm by 3/8:
25 3 5 3

1.SSS (side, side, side) SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. ...
2.SAS (side, angle, side) ...
3.ASA (angle, side, angle) ...
4.AAS (angle, angle, side) ...
5.HL (hypotenuse, leg)
The length of ab is D. 15
The first one, SAS Postulate
To find the probability of both of these occurring, you will multiply the probability of choosing a blue marble by the probability of choosing a purple marble (with no replacement after the first one).
Probability of choosing a blue marble: 17/120
Probability of choosing a purple marble: 18/119
17/120 x 18/119 = 3/140
You will have a 3/140 chance of both of these occurring.
