What is the probability that he will pass at least one subject?

The probability that he’ll pass at least one subject is 0.808.

How do you find the probability of passing an exam?

The probability of a person passing a test is calculated taking into account his performance in previous tests. For example, a person took 100 tests previously and passed in 98 of them. P(pass) now would be 98/100 (0.98).

What is the probability of passing exactly one?

2/12 + 3/12 = 5/12. So, there is a 5/12 probability that only one will pass.

Is the overall percentage of success in an exam is 60 What is the probability that out of a group of 4 students at least one has passed?

The probability of x=0 (with n=4, p=0.6) is 0.0256. So, the probability of at least 1 passed is 1-0.0256 or 0.9744.

What is the probability of getting 2 heads when 2 coins are flipped?

The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25. A visual representation of the toss of two coins.

How do you find the probability of one event occurring?

The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible. Converting the fraction 35 to a decimal, we would say there is a 0.6 probability of choosing a banana. This basic definition of probability assumes that all the outcomes are equally likely to occur.

How do you find the probability of exactly one?

The probability that exactly one of the events A and B occur is P(A and not B) + P(not A and B). The events A and B are independent, so P(A and not B) = P(A)P(not B) = p(1 − q) = p − pq.

When 2 coins are being tossed there are 4 possible outcomes What is the probability that the two coins will land 2 heads?

The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25. A visual representation of the toss of two coins. The Product Rule is evident from the visual representation of all possible outcomes of tossing two coins shown above.
