Use the random-number table to simulate the outcomes of tossing a quarter 25 times. Assume that the quarter is balanced (i.e., fair). (Start at row 1, and let 0, 1, 2, 3, 4 indicate heads and 5, 6, 7, 8, 9 indicate tails. Enter H for heads and T for tails,
1. If you flip a fair coin 10 times, what is the probability of a) getting all tails Is it 1/1024? b) getting all heads Is it 1/1024? c) getting at least one tails? Is it 1023/1024? 2. If you roll a pair of fair dice, what is the probability of a) getting
A biased coin lands heads with probabilty 2/3. The coin is tossed 3 times a) Given that there was at least one head in the three tosses, what is the probability that there were at least two heads? b) use your answer in a) to find the probability that there
A fair coin is tossed seven times. what is the probability of getting at least one tail?
