Competency 005 of the Core Subjects EC–6: Mathematics (902). The competencies TEA lists, how they are tested and practice questions with explanations.
40 questions on the real 70-minute clock, with a score by competency group and an explanation for every answer.
Or start the free Probability and Statistics drillSummarized from the TExES Core Subjects EC–6 (391) preparation manual, Section 3: exam framework, Competency 005. The grouping of competencies into drill sets is ours.
Questions give a data set, table or graph and ask for a measure of center or the best display, or ask for the probability of an event. TEA lists the competencies without weights, so our practice test spreads its questions evenly across them.
Answer each question, then open the explanation.
Question 1
A student has 3 shirts and 4 pairs of pants. How many different outfits of one shirt and one pair of pants can the student make?
Answer: B: 12
By the fundamental counting principle, multiply the choices: 3 × 4 = 12 outfits.
Question 2
Which value is the mode of 5, 7, 7, 8, 9, 9, 9, 10?
Answer: C: 9
The mode is the value that occurs most often. The number 9 appears three times.
Question 3
The weekly reading minutes for five students are 30, 45, 60, 90 and 120. What is the range?
Answer: B: 90
Range = greatest value − least value = 120 − 30 = 90 minutes.
Question 4
A coin is flipped and a number cube (1–6) is rolled. What is the probability of getting heads and a 6?
Answer: A: 1/12
The events are independent, so multiply: 1/2 × 1/6 = 1/12. There are 12 equally likely outcomes, and only one is heads with a 6.
