Question

Вероятность одного попадания в цель при одном залпе из двух орудий равна 0,38. Найти вероятность поражения цели при одном выстреле первым из орудий, если известно, что для второго орудия эта вероятность равна 0,8.

Answer 1

Вероятность будет равна Р=0,38:0,8=0,475

Answer 2

Problem Analysis

We are given that the probability of hitting the target with one shot from two guns is 0.38. We need to find the probability of hitting the target with the first gun if we know that the probability of hitting the target with the second gun is 0.8.

Solution

Let's denote the probability of hitting the target with the first gun as p1 and the probability of hitting the target with the second gun as p2. We are given that p1 + p2 = 0.38.

We are also given that p2 = 0.8.

To find p1, we can use the equation p1 + p2 = 0.38 and substitute the value of p2:

p1 + 0.8 = 0.38

Subtracting 0.8 from both sides, we get:

p1 = 0.38 - 0.8

Simplifying, we find:

p1 = -0.42

However, probabilities cannot be negative, so the value of p1 = -0.42 is not valid.

Therefore, it seems there might be an error in the given information or the problem statement. Please double-check the values provided.
