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
To find the probability of rolling a 4 on the number cube and the coin landing heads up, you need to determine the number of times these two events occurred together in the simulation.
From the table:
- Number 4 was rolled 23 times.
- Heads was flipped 48 times.
The number of times rolling a 4 and getting heads up is the smaller of the two values, which is 23.
Therefore, the probability is 23/100 = 0.23 or 23%.
