Answer:
The probability that the student will not guess correctly on any one question is 4/5
Step-by-step explanation:
The question posed is an application of the binomial probability distribution.
We have been informed that the test has multiple choice questions with 5 choices for each answer that only one answer is correct for each question.
If the student guesses the answer to each question, then the probability that the student will guess correctly on any one question is 1/5.
Therefore, the probability that the student will not guess correctly on any one question is;
1 - 1/5 = 4/5

Answer:
The family of directions of the given vector is represented by , .
Step-by-step explanation:
According to the given information, vector stands in the 4th Quadrant (, ) and direction of the vector () in sexagesimal degrees, is determined by following definition:
,
Please notice that angle represents a function with a periodicity of 360°.
If we know that and , then the direction of the vector is:
The family of directions of the given vector is represented by , .
