A national trend predicts that young professionals aged 22-28 will account for half of all business travelers in the next 3 years. To attract these young professional business travelers, hotels are moving their advertising campaigns to social media.

Find the probability that 4 of the hotels in the sample will post their ads on social media only. (Round your final answer to 4 decimals, record it as decimal number, e.g., if the answer is 89.12% record 0.8912)
