What is the probability of “at least one student prefers math”?

P (at least one student prefers math) = 1 – (.96)3 = .1153. This matches the answer that we got using the three-step process above. Use the following examples as additional practice for finding the probability of “at least one” success.

What is the probability that he answers at least one incorrectly?

The probability that he answers at least one incorrectly is 0.578. Use this calculator to automatically find the probability of “at least one” success, based on the probability of success in a given trial and the total number of trials.

How to find the probability of at least one success?

P (at least one prefers math) = 1 – P (all do not prefer math) = 1 – .8847 = .1153. It turns out that we can use the following general formula to find the probability of at least one success in a series of trials:

What is the probability of getting at least 1?

Solution: P(makes at least one) = 1 – P(misses a given attempt) P(makes at least one) = 1 – (0.80) P(makes at least one) = 0.672.

What does it mean by at least in probability?

Suppose, if we say two dice are thrown and the probability to get at least 8 means, we should get a minimum value of 8. At least also means “less than or equal to”. Therefore, in probability, at least mean the minimum value that should occur once a random event happens.

How do you find the probability of the most 1?

The easy way to do it: the probability that at most one event will occur is the same as the probability that not both will occur, that is, 1−P(A∩B) .

How do you find the probability of at least 3?

Example 1: Free-Throw AttemptsP(X≥3) = 1 – P(X=0) – P(X=1) – P(X=2)P(X≥3) = 1 – . 2373 – . 3955 – . 2636.P(X≥3) = 0.1036.

What is the probability that at least one fails?

(B) The probability that at least one component fails is 1 minus the probability that all succeed. Since the probability of one component succeeding is 1 minus 0.1, or 0.9, the probability that all succeed is (0.9)6 = 0.53, and 1–0.53 = 0.47.

What is the probability of getting at least 1 red?

Find probability of getting at least 1 red ball: (1520)2=(34)2=916 is the probability of not getting a red ball in the draw hence 1−916=716 is the probability of getting at least 1 red ball.

What is the probability of getting at least 2 heads?

1/2The probability of obtaining at least two heads is. = 1/2.

How do we calculate probabilities?

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.

What is the probability of a student passing math course?

The probability of a student passes math course is 1/3 and passes statics course is 1/4. If the probability to pass both courses is 1/6. What is the probability to pass one of both courses?

What is the probability of passing at least one class?

The probability of passing at least one class is 1 minus the probability of failing both.

What is the key point of ambiguity in the problem statement?

A key point of ambiguity in the problem statement is “a student”. If the problem is stating that students in general have these probabilities of passing, you might think that results for the three subjects are highly correlated, because they are all driven by overall intelligence. In the extreme, you might say that the 1/3 of the students who pass English would be the smart ones, and they would also pass math and science. This would make the answer be 1/3.

What does P mean in math?

P ( A U B U C )=> A or B or C or all 3.

What is the answer of the three outcomes if they are correlated?

If the three outcomes are correlated, the answer could be as high as 1/3 (33% ); or if they are anti-correlated, the answer could be zero.

Can 15/35 pass both algebra and geometry?

Let us take an example of a class of 35. Thus, 10/35 would pass algebra and 14/35 would pass geometry. So, it would not be possible for 15/35 to pass BOTH exams since that cannot be higher than either of the total who passed EACH exam.
