What is the probability?




Algebra problems
Try to solve this problem of calculating mathematical probability
Can the paratrooper be saved?

below you can see the answer and the detail solution.


Correct answer is 3/8 or 37,5%

The area of the minefield is  a^2/2 +2a^2/2 =3a^2/2
Total area is 2a.2a=4a^2

P=(3a^2/2) / (4a^2)=3/8 or 3/8 .100=37.5%
