What does it mean for two events to be independent in probability?

After a particular surgery, patients are placed in an intensive care unit (ICU) until their condition stabilizes. Then they are transferred to a special care ward (SCW), where they remain until they are released from the hospital. In a particular metropolitan area, a study of hospital records produced the following data: each day \( 2 \% \) of the patients in the ICU died, \( 49 \% \) were transferred to the SCW, and the remainder stayed in the ICU. Furthermore, each day \( 3 \% \) of the patients in the SCW developed complications and were returned to the ICU, \( 1 \% \) died while in the SCW, \( 22 \% \) were released from the hospital, and the remainder stayed in the SCW. A) In the long run, what percentage of the patients in the ICU are released from the hospital? \( \square \% \) (Round to two decimal places as needed.)

3. Combinations and Probabilities: 20 pts. You are tasked with creating a code using the following three conditions: 1. The code must consist of exactly 4 characters. 2. Each character can be one of the following: A, B, C, or D. 3. The code can repeat characters, but the first character must be different from the last character. How many different codes can you create based on these condi- tions? You MUST show all of your steps to receive full credit.

3. A six-sided die is rolled one time. Find the probability of getting an even number greater than 2 .

e. ¿Cuál es la longitud medida de la cola? 5. Un supermercado tiene una caja de pago donde los clientes llegan siguiendo un proceso de Poisson con una tasa de llegada de 10 clientes por hora. Los cajeros en la caja procesan a los clientes de acuerdo con una tasa de servicio de 15 clientes por hora. a. ¿Cuántos clientes, en promedio, se encuentran en el sistema? b. ¿Cuánto tiempo, en promedio, pasa un cliente en el sistema? c. ¿Cuántos clientes, en promedio, están esperando en la cola?

The expected value of betting \( \$ 1 \) on one roulette number is approximately \( -\$ .05 \). What does this mean in practical terms? If many people made this bet over the course of the night, the house would expect to take in approximately a \( 5 \% \) return. If I bet \( \$ 1 \) one time, I would expect to leave the table with approximately 95 cents. I am almost guaranteed to lose this bet I am almost guaranteed to win this bet
