There are 24 people. 9 have black hair, 4 have brown hair, 5 have blonde hair, and 6 have red hair. 3 people are then selected at random without replacement. Solve the following probabilities: (a) What is the probability that all 3 people selected have red hair. (b) What is the probability that 2 people selected have the same color hair color, and the other person selected has a different hair color

A group of 120 students, 7 have black hair, 35 have blond hair, 12 have red hair, and the remaining have brown hair. If a student is selected uniformly at random from the group, the probability that the student has black hair or blond hair can be expressed as a fraction a/ba/b, what is such fraction?

An individual can be classified by gender as male, female, by hair color as black, blonde, brown, red, unknown, and by eye color as black, brown, green, hazel, unknown. a) How many different classifications are possible (for example, male, with blonde hair, and green eyes)? There are different classifications. b) Construct a tree diagram to determine the sample space. The tree for gender has branches. From each branch of the tree for gender, the tree for hair color has branches...

1. A room contains one-hundred people. Each person has hair that is either black, blonde, brown or red in colour. There are as many people with black hair as there are people with blonde, brown or red hair. Write down a linear system of two equations in four unknowns that encodes this information, and also write down the corresponding augmented matrix. So, the equations I got were: 25b+25l+25r+25d=100 b+l+r+d=100 is that correct? I am not sure.

There are 40 students in a classroom at UT-Almost. Thirty of these students started as freshmen at UT-Almost; the rest are transfers. The transfer students are split evenly between Business Majors and Liberal Arts majors. The total number of Business majors is 25. 15a. Suppose we randomly selected a single student and he/she turns out to have started at UT-Almost. What is the probability he/she will be a Business Major? 15.b. Suppose we randomly selected two students using this process:...
