Answer:
The likelihood that a point chosen inside the square will also be inside the circle: 78.54%
Step-by-step explanation:
- Let x is the side of the suqare
=> the area of the square is: 
- Let d is the diameter of the circle
=> the area of the circle :
π
However, d=x because of the square property
<=> the area of the circle :
π
The likelihood that a point chosen inside the square will also be inside the circle:
the area of the circle / the area of the square
=
π /
=
π *100%
= 0.7854 * 100%
= 78.54%
