Question 953771: 1. There is a 30% chance when you arrive at a stop light it is red? Express this as a probability value.
2. There is a 40%chance class will be cancled. Express as a probability value.
3. (Disjoint or not disjoint) a. Getting to work early for your next class.
b.not gstting to work early for your next class.

1. There is a 30% chance when you arrive at a stop light it is red? Express this as a probability value.

x = event that when you arrive at a stop light, it is red.
p(x) = .30

2. There is a 40% chance class will be canceled. Express as a probability value.

y = event that a class will be canceled.
p(y) = .40

3. (Disjoint or not disjoint)

a. Getting to work early for your next class.
b. Not getting to work early for your next class.

a and b are disjoint because you can't get to work early for your next class and not get to work early for your next class at the same time.
The events are mutually exclusive, therefore disjoint.
