What is the probability of hitting a target?
0.2
The probability of hitting a target in any shot is 0.2 .
What is the probability that the target was hit at least twice given that it had been hit at least once?
The probability of hitting a target at least twice, conditioned on hitting it at least once. The probability of hitting a target is 15. Ten shots are fired independently.
What is the probability that none of them will hit the target?
The probability for none of them hitting is easiest as there’s only one scenario – everyone misses – so 1/2 * 1/3 * 1/4 = 1/24.
What is the general multiplication rule?
The multiplication rule is a way to find the probability of two events happening at the same time (this is also one of the AP Statistics formulas). The general multiplication rule formula is: P(A ∩ B) = P(A) P(B|A) and the specific multiplication rule is P(A and B) = P(A) * P(B).
What is the probability of making 3 correct cases in 5 true/false answer type questions?
0.3125
What is the probability of making 3 correct guesses in 5 True – False answer type questions? 0.3125.
What is the probability of getting 53 Sundays in leap year?
7
The probability that a leap year selected at random contains 53 Sunday is (1)7/366 (2)28/183 (3) 1/7 (4) 2/7. We know that a leap year has 366 days. So, we have 52 weeks and 2 days. Hence, a leap year has 52 Sundays.
What is the probability of getting 53 Sundays?
1 / 7
In 365 days, Number of weeks = 52 weeks and 1 day is remaining. 1 remaining day can be Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday. Total of 7 outcomes, the favourable outcome is 1. ∴ probability of getting 53 Sundays = 1 / 7.
What is the probability of hitting the target exactly 5 times?
Well if I understand the question correctly .. the “probability” remains the same at 3/5 = 60\% . So the answer would be “0” to hit the “Target exactly 5 times”. The shooter hits the target 3 out of 5 shots, takes another 5 shots hits the Target 3 times again.
What is the probability that at least one hit doesn’t happen?
So the probability that the event “at least one hit” doesn’t happen is ( 3 / 4) 4. So the probability that the event “at least one hit” does happen is 1 − ( 3 / 4) 4. Thanks for contributing an answer to Mathematics Stack Exchange!
What is the probability of getting Mmmm with no hits?
It is much easier to find the probability of no hits, which is the probability of getting MMMM. This is ( 3 / 4) 4. So the probability that the event “at least one hit” doesn’t happen is ( 3 / 4) 4. So the probability that the event “at least one hit” does happen is 1 − ( 3 / 4) 4.
What is the probability of success of a Bernoulli experiment?
The probability of success on each trial is p = 1=2 and the probability of failure is q = 1 1=2 = 1=2. We are interested in the variable X which counts the number of successes in 12 trials. This is an example of a Bernoulli Experiment with 12 trials.
