In a bundle of 50 shirts, 44 are good, 4 have minor defects and 2 have major defects. What is the probability that :
(i) it is acceptable to a trader who accepts only a good shirt .
(ii) it is acceptable to a trader who reject only a shirt with major defects ?

The correct Answer is:
To solve the problem step by step, we will determine the probabilities for both parts of the question. ### Step 1: Understand the total number of shirts and their conditions - Total shirts = 50 - Good shirts = 44 - Shirts with minor defects = 4 - Shirts with major defects = 2 ### Step 2: Calculate the probability for part (i) **(i) Probability that it is acceptable to a trader who accepts only a good shirt.** 1. **Identify the favorable outcomes:** - The trader only accepts good shirts. - Therefore, the number of favorable outcomes (good shirts) = 44. 2. **Identify the total outcomes:** - The total number of shirts = 50. 3. **Calculate the probability:** \[ P(\text{Good shirt}) = \frac{\text{Number of good shirts}}{\text{Total number of shirts}} = \frac{44}{50} = \frac{22}{25} \] ### Step 3: Calculate the probability for part (ii) **(ii) Probability that it is acceptable to a trader who rejects only a shirt with major defects.** 1. **Identify the favorable outcomes:** - The trader rejects shirts with major defects. - Therefore, the number of shirts that are acceptable = Total shirts - Major defect shirts = 50 - 2 = 48. 2. **Identify the total outcomes:** - The total number of shirts = 50. 3. **Calculate the probability:** \[ P(\text{Acceptable shirt}) = \frac{\text{Number of acceptable shirts}}{\text{Total number of shirts}} = \frac{48}{50} = \frac{24}{25} \] ### Final Results - The probability that it is acceptable to a trader who accepts only a good shirt is \( \frac{22}{25} \). - The probability that it is acceptable to a trader who rejects only a shirt with major defects is \( \frac{24}{25} \). ---
