Dan used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. The results are shown in the tables below:
Number on the Cube Number of Times Rolled
1 19
2 26
3 13
4 23
5 8
6 11
Heads Tails
48 52
Using Dan's simulation, what is the probability of rolling a 4 on the number cube and the coin landing heads up? (1 point)
48 over 100
71 over 100
1002 over 10000
1104 over 10000
The probability of rolling a 4 on the number cube and the coin landing heads up is 23 (number of times rolled a 4) + 48 (number of times landed heads up) / 100 (total number of rolls).
Therefore, the probability is 71 over 100.
