The answer of the above question is letter <em>C. proof by contradiction</em>. It is a type of proving where the evidence does not support the reverse assumption crediting the original statement as true. This proof can also be referred as "reductio ad absurdum" which are Latin word for "reduced to an absurdity"

t hits the square dartboard shown below at a random point. Find the probability that the dart lands in the shaded circular regio
masha68 [24]

Given:

Required:

To find the probability that the dart land will be in the shaded region.

Explanation:

Area of the circle is given by the formula:

A=\pi r^2

Where r = radius

Thus the area of the circular region

\begin{gathered} =(3.14)\times(2)^2 \\ =3.14\times4 \\ =12.56\text{ square in.} \end{gathered}

The area of the square is given by the formula:

=(side)^2

Thus the area of the given square

\begin{gathered} =(6)^2 \\ =36\text{ square in.} \end{gathered}

The probability of an event is given by the formula:

P=\frac{number\text{ of possible outcomes}}{Total\text{ number of outcomes}}

The probability that the dart land will be in the shaded region

=\frac{Area\text{ of the shaded region}}{Area\text{ of the square}}

Thus probability

\begin{gathered} P=\frac{12.56}{36} \\ P=0.3488 \\ P=0.349 \end{gathered}

Final answer:

Thus the probability that the dart land will be in the shaded region is 0.349.

T (2/4, 1 2/4)

E ( 1 2/4, 1)

I ( 3/4, 3/4)

R (1 3/4, 1/4)

Step-by-step explanation:

Can't really explain but ill try:

I believe that it is going by 0.25 meaning it would be just like going by oen but instead its .25....does that make sence??
