Describe the difference between passing a parameter of a primitive type and passing a parameter of a reference type. Show the output of the following programs:

Public class Test {
  public static void main(String[] args) {
    Count myCount = new Count();
    int time = 0;

    for (int i = 0; i < 100; i++ )
      increment(myCount, time);
    System.out.println("count is" + myCount.count);
   }
 
 public static void increment (Count c. int time) {
   c.count++
   times++
  }
}

public class Count {
  public int count;

  public count (int c){
   count = c;
 }
 
 public Count () {
   count = 1;
  }
}

According to the travel information, what's the probability that someone who has traveled to Mexico has visited Canada too?

For many people, breakfast cereal is an important source of fiber in their diets. Cereals also contain potassium, a mineral shown to be associated with maintaining a healthy blood pressure. An analysis of the amount of fiber (in grams) and the potassium content (in milligrams) in servings of 77 breakfast cereals produced the linear model $\widehat{\text {Potassium}}$= 38 + 27 Fiber. If your cereal provides 9 grams of fiber per serving, how much potassium does the model estimate you will get?
