Statistics on Covid-19 deaths gave the following breakdown by age-group for the first 1624 deaths in Italy in 2020:

a. What is an appropriate sample space for studying the probability distribution represented by this table?

b. What are examples of relevant events on your chosen sample space?

c. Give a rough sketch of the bar-plot that represents the probability distribution in the table above. (Remember that probabilities are numbers between 0 and 1.)

d. In this sample space, what is the probability that a death corresponds to a person aged under 50? What method of combining events are you using when you do this calculation: intersection or union?

e. Can you assume that the same probability distribution applies to COVID-19 deaths in other sample spaces, for example in other countries? Why or why not?
Being ambidextrous means having equal ability in both hands. It’s very rare, applying to only about 1% of the population.
