Using complementary angles, <X is equal to <Z, so it's <Z = 35°.
Answer:
Step-by-step explanation:
If we call x the number of correct answers, we can said that P(x) follows a Binomial distribution, because we have 25 questions that are identical and independent events with a probability of 1/4 to success and a probability of 3/4 to fail.
So, the probability can be calculated as:
Where n is 25 questions, p is the probability to success or 0.25 and q is the probability to fail or 0.75.
Additionally,
So, the probability that the student answers more than 20 questions correctly is equal to:
Where, for example, P(21) is equal to:
Finally, P(x>20) is equal to:
