Answer:
a) 2.5 shots
b) 59.4 shots
c) 4.87 shots
Step-by-step explanation:
Probability of making the shot = 0.6
Probability of missing the shot = 0.4
a) The expected number of shots until the player misses is given by:
The expected number of shots until the first miss is 2.5
b) The expected number of shots made in 99 attempts is:
He is expected to make 59.4 shots
c) Let "p" be the proportion shots that the player make, the standard deviation for n = 99 shots is:
The standard deviation is 4.87 shots.
Answer:

Step-by-step explanation:
Let us divide the shape into two rectangles and a right triangle. The resulting composite figure is attached.
As we see in the figure the area of the triangle is
.
The area of the bigger rectangle is (it's actually a square )
,
and the area of the smaller rectangle is
.
Therefore, the total area of the shape is
Answer:
It's 1/21
