Question

вероятность того что при выстреле первый стрелок попадет в мишень, равна 0,8, вероятность того, что стрелок попадет в мишень -0.85 какова вероятность того чтт в мишень попадет хотя бы один стрелок

Answer 1

Probability of the First Shooter Hitting the Target

The given information states that the probability of the first shooter hitting the target is 0.8. This means that out of every 10 shots fired by the first shooter, we can expect 8 of them to hit the target.

Probability of Any Shooter Hitting the Target

The information also states that the probability of any shooter hitting the target is 0.85. This means that out of every 10 shots fired by any shooter, we can expect 8.5 of them to hit the target.

Probability of at Least One Shooter Hitting the Target

To find the probability of at least one shooter hitting the target, we can use the concept of complementary probability. The complementary probability of an event A is equal to 1 minus the probability of the event not occurring.

In this case, the event A is at least one shooter hitting the target. The complementary event is no shooter hitting the target. Therefore, the probability of at least one shooter hitting the target is equal to 1 minus the probability of no shooter hitting the target.

To calculate the probability of no shooter hitting the target, we can use the probability of any shooter missing the target, which is 1 minus the probability of any shooter hitting the target. So, the probability of no shooter hitting the target is 1 - 0.85 = 0.15.

Therefore, the probability of at least one shooter hitting the target is 1 - 0.15 = 0.85.

Please note that the above calculations are based on the given probabilities and assumptions.
