b) When you subtract a positive number from a negative
number the answer is negative. __

c) When you subtract a negative number from a positive
number the answer is negative. __

d) When you subtract a negative number from a negative
number the answer is negative. __

see answers below

Step-by-step explanation:

A 'This statement is always true'

B 'This statement is sometimes true'

C 'This statement is never true'

a) When you add two negative numbers the answer is negative. _A_

e.g. -4 + -1 = -5

b) When you subtract a positive number from a negative

number the answer is negative. _A_

e.g.  -5 - (+4) = -9

c) When you subtract a negative number from a positive

number the answer is negative. _C_

e.g. 5- (-2) = 8   always positive, => never negative

d) When you subtract a negative number from a negative

number the answer is negative. _B_

-2 - (-4) = +2

-2 - (-1)  = -1

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
