Ivan is conducting an experiment on probability. He has placed six marbles of different colors into a bag. He draws one marble,
records its color, replaces it, and draws another. So far he has drawn 258 marbles. He expected that he would draw the red marble
on 1 out of every 6 draws, but this is not what his results show. What is the best reason why Ivan has not drawn the red marble the
number of times that he expected?
A. Because he should be drawing two marbles at a time
B. He forgot to replace the red marble in the bag once
C. because he has not drawn enough marbles
D. the problaity is a theory not a fact it is the chance that an event will occur

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
