a) For every 1 point, Yehudi wins 0.35 points.

Thus, for 15 points, Yehudi will win $15 \times 0.35= 5.25$ points.

b) You know what to do :)

When you repeat the same experiment over and over, and all experiments are independent, you are following a Bernoulli distribution. If you perform n experiments, and you have probability of succeeding p for each experiment, the expected number of successes is

\mathbb{E}(X)=np

In your case, you perform 15 experiments, with a probability of success of 0.35 per experiment. So, we expect

np=15\cdot 0.35=5.25

Since 10 is about twice the number of expected points, it would be very surprising.

<h3>Answer:  110 square miles</h3>

=============================================================

Explanation:

There are a few ways to do this.  

One method involves drawing a horizontal line to form three rectangles as show below. Note the labels A,B,C.

  • Rectangle A in the upper left corner has area of base*height = 6*7 = 42 square miles. I'll let A = 42 since we'll use it later.
  • Rectangle B is 20 miles across horizontally (base) and 2 miles tall vertically (height). The 2 miles is from 9-7 = 2. The area of rectangle B is 20*2 = 40 square miles. Let B = 40.
  • Then finally, C = 28 because rectangle C is 4 miles across and 7 miles tall, so 4*7 = 28.

Add up those three sub areas found: A+B+C = 42+40+28 = 110 square miles

----------------

There are other methods you could do. A second method is to draw two vertical lines to form 3 other rectangles, then add up the sub areas to get 110.

A third method is to draw a horizontal line across the top to form one large rectangle (20 mi by 9 mi) and subtract off the area of the 7 mi by 10 mi inner rectangle (the empty space), so you'd say 20*9 - 7*10 = 180-70 = 110
