If we roll two dice 108 times, how many times can we expect the dice to show a sum of six
Since the first toss won't matter (you need either heads or tails), it can be discarded. Dealing with the remaining two tosses: 1/2 * 1/2 = 1/4 So there's a 1/4 chance of getting just that.
okay lolrichie, I gave you an incorrect answer to see if you are paying attention. you are simply noting down whatever I say. How do you know I am giving you the right answer? do you know how to do these problems at all? do you understand the concept of probability?
yea i noticed that because its multiple choice
then why didn't you say anything? you simply gave another problem. do you understand probability or not?
