The mathematics department of a college has 5 male professors, 11 female professors, 9 male teaching assistants, and 5 female teaching assistants. if a person is selected at random from the group, find the probability that the selected person is a teaching assistant or a female.

We need the total count of persons = 5 + 11 + 9 + 5 = 30 persons

We need the count of the target group, female or teaching assistants

= 11 female professors + (9+5) teaching assistants

= 11 + 14

= 25 persons

Assuming equal probability of choosing anyone from the 30 persons, the

probability of choosing a female or teaching assistant

= 25/30

= 5/6

(For probability calculations, try to keep a fraction for as long as you can, because fractions are exact. Decimal are frequently approximate, for example in this case, 5/6=0.83333 = 0.833 approximately)

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
