Eric uses a random number generator to simulate the results of a coin toss. He assigns the number 0 to heads and the number 1 to tails. If 1,000
numbers are generated, how many heads can he expect?

hi the correct answer I believe would be 500

Step-by-step explanation:

since it's a 50 out of 50 chance (because it is heads and tails) the only logical way of thinking this through would be half and half

what I did was simply divide 1,000 by 2 to get 500 so there are 500 heads to be expected.

I hope I was any help to this

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.

it has to have an angle of 90 degrees
