Answer:

P = 0.07

Step-by-step explanation:

To find the probability, we need to find the area of the circular dashboard and the area of the square shaded region.

The area of the circle is calculated as

Ac = πr²

Where π = 3.14 and r is the radius. So, replacing r = 13 in, we get

Ac = (3.14)(13)²

Ac = (3.14)(169)

Ac = 530.66 in²

On the other hand, the area of the square is

As = s²

Where s is the side, so replacing s = 6 in, we get:

As = 6²

As = 36 in²

Now, the probability that the dart lands in the shaded square region is the area of the square divided by the Area of the circle, so

P = As/Ac

P = 36/530.66

P = 0.07

So, the answer is 0.07
