... • The probability that you encounter a green light at the corner of Dan Allen and Hillsborough is 0.35, a yellow light 0.04, and a red light 0.61. What is the probability that you encounter a red light on both Monday and Tuesday? • It’s reasonable to assume that the color of the light you encounter ...

Tree Diagrams
... When dealing with probability, it is helpful to think about the “sample space”, which is the complete list or representation of all the possible outcomes of an event. There are many ways that a “sample space” can be represented such as contingency tables, lists, pictures, or tree diagrams. This work ...

... • The answer is .3413 (read as 1.0 under 0.00). • This was quite easy because the lower bound was at the mean (or zero). • Most problems will not have the lower bound at the mean. • Nevertheless the normal table can be used to calculate the relevant probabilities by the addition or subtraction of ap ...
