Answer:
<h2>The probability of first one to be blue is
.</h2>
Step-by-step explanation:
In the given box, there are 4 red markers and 2 blue markers.
The given scenario will not affect the required probability as the selection of the second one is a case of future.
We need to find the probability of the first marker is blue.
The probability is 
.
Assuming all angles are to be calculated.
Using the cosine rule:
a^2=b^2+c^2-2bc(cos(A))
=>
cos(A)=(b^2+c^2-a^2)/(2bc)
substitute values,
cos(A)=(17^2+19^2-22^2)/(2*17*19)=83/323=0.25697
A=75.11 degrees
similarly
cos(B)=(19^2+22^2-17^2)/(2*19*22)=139/209=0.66507
B=48.31 degrees
cos(C)=(22^2+17^2-19^2)/(2*22*17)=103/187=0.55080
C=56.58 degrees
Check: (75.11+48.31+56.58)=180.00 degrees, ok.
Note:
1. Better accuracy than required is calculated for a more accurate check. You need to round answers to the specified accuracy.
2. In fact, not all tables are made from formulas. Some tables are compiled by experimentation and require hundreds and thousands of man-years to complete (e.g. steam tables).
