Consider the hospital emergency department visits shown in table below. People may leave without being seen by a physician, and those visits are denoted as LWBS. The remaining visits are serviced at the emergency department, and the visitor may or may not be admitted for a stay in the hospital. Hospital 1 2 3 4 Total Total 5301 7076 5828 4378 22583 LWBS 194 265 242 231 932 Admitted 1247 1558 698 964 4467 Not admitted 3860 5253 4888 3183 17184 Assume that the records are reviewed from two visits selected randomly without replacement from the table. (a) What is the probability that the second visit selected is LWBS given that the first visit selected is LWBS? Round your answer to four decimal places (e.g. 98.7654). P = i (b) What is the probability that both visits are LWBS from hospital 4? Round your answer to six decimal places (e.g. 98.765432). P = i
