If a point is chosen inside the square, what is the probability that it will also be inside the circle?

Feliz [49]

Answer:

$79\%$

Step-by-step explanation:

The probability that the point is chosen in the circle is equal to the area of the circle divided by the area of the square.

Formulas used:

Area of a square with side length $s$ is given by $A=s^2$
Area of a circle with radius $r$ is given by $A=r^2\pi$

The segment marked as 1 represents not only the radius of the circle, but also half the side length of the square. Therefore, the side length of the square is 2, and we have:

Area of square: $A=2^2=4$

Area of circle:

$A=1^2\pi=\pi$

Therefore, the probability that the point will be inside the circle is:

$\frac{\pi}{4}=0.78539816339\approx \boxed{79\%}$

What is the bottlencek effect?.

marusya05 [52]

{If this is a biology question}

The bottleneck effect can be explained by the cheetah population. Cheetah's used to be unique and many before they were hunted. Their population dropped so low, breeding produced almost exact 'clones'. The bottleneck effect is when genetic diversity is lost.
