zion's drive to work has 4 lights. she is trying to make sure she is on time to work every day, so for a month she tracked how many times she hit a red light out of her 4 lights and created the model below showing the probability of hitting anywhere from zero to 4 red lights X 0 1 2 3 4 P(X)   .27 .35 .17 .16 what is the probability of hitting no red lights? what is the expected average number of red lights she would hit every day? what is the expected standard deviation of red lights?

You want to study the probability of a single slug surviving one day after excessive heat exposure, so you design an experiment where you expose 100 slugs to a temp of 40 degrees Celcius for 6hrs then record the casualties and survivals after 24hrs. In the end, 45 slugs died.    a. Determine the probability of all possible events b. Based on your experimental results, determine the probability of the single snail surviving c. How many individuals would you expect to survive after 24hrs from exposure if the experiment was run with 520 slugs instead of 100?

Lompete your answers on a separate sheet of paper and upload to the assignment posted for this test. Ti A 5. Roughly 2.19% of the US population has red halr. Of those with red hair, approdmately 20% have green eyes. Of the US population who do not have red hair approdimately 2% have green eyes. 1. (a). What is the probability that a randomly selected person from the US does not have red hair and does not have green eyes? (b) Given that a randomly selected person from the US does not have red hair, what is the probability that they have green eyes? (c) Given that a person from the US does not have green eyes, what is the probability that they do not have red hair? (d) What is the probability of randomly selecting a person from the US that has green eyes? (e) Given that a randomly selected person from the US does have green eyes, what is the probability that they have red hair? () Assuming that the population in the US is very large (it is!), what is the probability of randomly selecting…
