If a die (a fair die -- a cube) is rolled one time, find the probability of getting: #s 4 or 6; an odd #; a # greater then 2; a # less than 4 and odd; a # divisible by 3. 9 Note: Use the formula for classical (theoretical) probability. Extra: A couple has four children. Find the probability that two of them are girls.

The test scores of a class of students are presented by the following date set:
88, 86, 66, 50, 65, 90, 98, 100, 76, 89, 66, 89, 88, 90, 91, 90, 40, 77, 82, 86
Note: Recall the definitions of measures of central tendency.
10Extra: Subtract 5 points from each score. How would requested measures of
average change? Generalize and make a conjecture. Find and compare ranges /
midranges of both data sets.
Find the mean, median, and mode.

Transcribed Image Text:Evaluate.
|11(x-(- 7)) when x = – 18and- 2a + 5a + 0.11 when a =- 2
Note: Recall what evaluation of an algebraic expression does mean.
Extra: Construct/solve (evaluate) an algebraic expression where the Distributive
Propertyto be applied twice.
