Answer:
CD is the name of a ray in the drawing ⇒ 3rd answer
Step-by-step explanation:
A ray is a part of a line that has one endpoint and goes on infinitely in only one direction.
From the drawing:
∵ CA has C as a starting point
∵ A is a point on it
∵ Its direction from C to A
∴ CA is a ray
∵ CB has C as a starting point
∵ B is a point on it
∵ Its direction from C to B
∴ CB is a ray
∵ CD has C as a starting point
∵ D is a point on it
∵ Its direction from C to D
∴ CD is a ray
∵ CF has C as a starting point
∵ F is a point on it
∵ Its direction from C to F
∴ CF is a ray
From the answer:
CD is the name of a ray in the drawing
The required formula is:

Therefore the probability of A given B is:
A) Taken at a basketball championship, the sample must be considered to be biased—probably in favor of basketball. Any conclusion can only be applied to attendees polled at the championship.
b) If a conclusion is to be drawn about opinions of students at the school, then a method needs to be devised to obtain opinions from a random sample of students. Likely, care would need to be taken to ensure expressed opinions are not influenced by games scheduled or just concluded, or by other factors such as reported injuries. A random sample from a list of student ID numbers might be appropriate. The poll might need to be conducted between seasons.
The answer is 60.
You must first solve what is in parentheses.
