A toy manufacturing company has categorised all the toys they make into 4 categories depending on the battery life of toys (assuming all the toys they manufacture run on battery). It is assumed that the toys belonging to category 1 will last for more than 50 hours with probability 0.4, while the corresponding probabilities for toys belonging to categories 2, 3, and 4 are 0.5, 0.8, and 0.2 respectively. Suppose that 30% of the toys are in category 1, 20% in category 2, 10% in category 3, and 40% in category 4. Sarah went to the toy manufacturing company and randomly picked one toy. If the toy did not last for more than 50 hours, what is the probability that she picked the toy from category 4 (assuming the toy was in use until the battery life got over)? Enter the answer upto 3 decimal accuracy. |
