What is the probability for a student to pass mathematics?
The probabilities that a student passes in mathematics, physics and chemistry are m,p and c respectively. Of these subjects, a student has a 75% chance of passing in at least one, a 50% chance of passing in at least two, and a 40% chance of passing in exactly two subjects.
What is the probability that 2 or more students do not pass the exam on their first attempt?
The probability that a person passes a test on the first try is 0.65. The probability that a person who fails the first test on the second try is 0.75. The probabilty that a person who fails the first and the second test will pass the third time is 0.60.
What is the probability that a random student passes the exam?
In exams, 80% of the students go prepared and 20% go unprepared. From the prepared ones, 90% passes the exams. From the unprepared one, only 10% passes the exams.
What is the probability that he will pass at least one of these subjects?
The probability of passing in at least one subject is actually the P(Math or English) i.e. P(A or B) Substitute the values, Therefore, the probability that he’ll pass at least one subject is 0.808.
What are the odds in Favour of Pinder failing both exams?
Pinder has examinations coming up in data management and biology. He estimates that his odds in favour of passing the data-management examination are 17:3 and his odds against passing the biology examination are 3:7.
What is the probability that at least one of them will solve the problem?
To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1. That is, P(at least one) = 1 – P(none).
Is 0 a real number Yes or no?
Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers.
