0.183. This problem addresses Binomial Probability. The formula is nCx × p^x × q^(n - x), where p = 0.72 and q = 1 - p = 0.28. With x representing the number of successes equal to 9 and n being 10, we are calculating the probability that at least nine out of ten people utilized an online travel website for booking. At least 9 out of 10 translates to x ≥ 9, so we calculate P(x ≥ 9) for x = 9 and x = 10. This leads to: P(x ≥ 9) = 10C9 × (0.72^9 × 0.28^(10 - 9)) + 10C10 × (0.72^10 × 0.28^(10 - 10)), resulting in approximately P(x ≥ 9) = 0.183.
Answer: 18 minutes
Step-by-step explanation:
The difference between the two endpoints needs to be calculated to ascertain the range, which results in 18.
Response: The outcome is 12
Detailed explanation: This is due to the fact that the least common multiple (LCM) of each number is 12. For instance, 4,8,12 and 3,6,9,12 will yield 6,12
