Scott has surveyed 29 classmates about the number of pets in their household and received the following frequency table: Number 0 1 2 3 4 Frequency 2 4 4 6 5 5 6 4 4 Let A be the event in which for a randomly selected classmate the number of pets in their household is 1 and let B be the event in which for a randomly selected classmate the number of pets in their household is 6. Find the following probabilities: P(A or B) = (Round the answer to 4 decimal places.) P(A and B) = (Round the answer to 4 decimal places.)
