A player of a video game is confronted with a series of 4 opponents and an 80% probability of defeating each opponent. Assume th

at the results from opponents are independent (and that when the player is defeated by an opponent the game ends). (a) What is the probability that a player defeats all 4 opponents in a game? Upper P equals left-parenthesis 0.8 right-parenthesis Superscript 4 Baseline equals 0.4096 (b) What is the probability that a player defeats at least 2 opponents in a game? Upper P equals 1 minus 0.2 minus 0.8 times 0.2 equals 0.64 (c) If the game is played 3 times, what is the probability that the player defeats all 4 opponents at least once? Probability defeats all 4 in a game = 0.84 = 0.4096. Probability defeats all four at least once = 1 – (1 – 0.4096)3 = 0.7942.

Answer:

117.5 ft²

Step-by-step explanation:

To find the area of the shaded area, we can find the area of the square, then subtract the areas of the two semicircles.

First, we will find the area of the given square, by using the formula lw, multiplying the length and width. The dimensions of this square are 14×14.

14 · 14 = 196

The area of the square is 196 ft².

We can now find the area of the two congruent half-circles. Since they are identical, we can simply find the area of one circle if it was whole. To find the area of a circle, we'll use the formula A=\pi r^2. With some simple deduction, we can see that the diameter of the circle is 10 ft, so the radius would be 5 ft long. Plug our values into the formula.

A = \pi5²

We will use 3.14 for \pi.

A = 78.5

The area of both the semicircles is 78.5 ft².

Now, we can subtract.

196 - 78.5 = 117.5

The area of the figure is 117.5 ft².

Good luck ^^
