government data assign a single case or each death that occurs in the u.s. the data show that the probability is 0.45 that a randomly chosen death was due to cardiovascular disease, and 0.22 that i was due to cancer. Suppose a docote checked the cause of death of 2 randomly selected patients. Define a random variable X as the number of patients whose cause of death was cardiovascular disease

What is the sample space of this random process?

What is the probability for the event {DD}, both were dead from cardiovascular disease.

What is P(x=0)?

What is the probability distribution of x?

mean for x?

standard dievation or x?
