Solution

The problem is asking for the probability that at least 2 shots hit the target.

First, let's calculate the individual probabilities of hitting the target for each person:

  1. Ramu: He can hit the target 3 times in 6 shots. So, the probability of Ramu hitting the target is 3/6 = 0.5
  2. Siva: He can hit the target 2 times in 6 shots. So, the probability of Siva hitting the target is 2/6 = 0.33
  3. Shyam: He can hit the target 4 times in 4 shots. So, the probability of Shyam hitting the target is 4/4 = 1

Next, we need to calculate the probability that at least 2 shots hit the target. This means we need to consider the following scenarios:

  1. Two shots hit the target: This can happen in three ways - Ramu and Siva hit, Ramu and Shyam hit, or Siva and Shyam hit. The probability for this is (0.50.33) + (0.51) + (0.33*1) = 0.165 + 0.5 + 0.33 = 0.995
  2. Three shots hit the target: This can only happen if all three hit the target. The probability for this is 0.50.331 = 0.165

Adding these probabilities together gives us the total probability that at least 2 shots hit the target, which is 0.995 + 0.165 = 1.16. However, probabilities cannot be greater than 1, so there seems to be a mistake in the problem or in our calculations.

Please check the problem and the calculations again.
