I am struggling with these questions while practicing with a test. I am looking for solution for these question but would like a explanation on how to do it not just answers as I am trying to learn how to do similar problems.

Below I posted the 3 questions I am struggling with:

(3... but: E Etta 20.4_ \"'02 0.0 12345673910 0 Age at Death (years) FIG. 4.13 The hypotheticai cumulative probability function for a population of sh. 4.9 Problems 1. The state of Wyoming (U.S.A.) lies between longinldes 104W and \"PW, and between latitudes 41N and 4554. Meteorites strike the Eah at random with respect to space and time. What is the probability that the next meteorite that arrives will strike Wyoming on a Tuesday if: a. We know in advance that the meteorite is traveling along a path par- allel to the Earth's axis and will arrive from the north? b. The direction of the meteorite's approach is purely a matter of chance? In this case. there is equal probability that the meteorite will strike any location on Earth. 2. In a hypothetical population of sh, the cumulative probability of dying follows the curve shown in gure 4.13. All sh die by the time they are 10 years old, and the equation for the curve shown is 2 P(age at death 1: x) = (ix0) . a. What is the probability density function for this population? b. How likely is it that a sh will die between the ages of3 and 4 years? 3. You are working with a population of sunowers whose heights are normally distributed with a mean it = 2.3 meters and a standard deviation cr = 0.5 meters. a. If you pick a plant at random from this population, what is the prob- ability that the height of this sample is between 2.6 and 2.9 meters? b. if you pick a plant at random, what is the probability that its height is exactly l.9 meters
