To understand the population the researcher explored the number of days NZ students were

absent during a 5 day school week.

Days Absent 0 1 2 3 4 5

Probability 0.742 ??? 0.035 0.021 0.018 0.011

1) What is the probability that a randomly selected student misses 1 day during the week (show

work)?

2) In the long run, what is the expected number of days a NZ high schooler will miss during a

typical week (show work or screen shot).
