Consider the hospital emergency room data displayed below, Let A denote the event that a visit is to hospital 4, and let B denote the event that a visit results in LWBS (at any hospital). Determine the following probabilities. Round your answer to three decimal places (eg. 98.765). Hospital 1 2 3 4 Total LWBS 193 270 243 245 951 Admitted 1278 1558 664 985 4485 Not 3820 5160 4724 3102 16806 admitted Total 5291 6988 5631 4332 22242 (3) P(A |B)= (b)P(A' |B) = (CP(A|B) = 1 () P(BIA)
