To find the probability of rolling a 4 on the number cube and the coin landing heads up, we need to calculate the total number of times a 4 was rolled and the coin landed heads, and then divide that by the total number of trials.
According to the table:
- Number of times 4 was rolled: 28
- Number of times the coin landed heads: 44
To find the total number of trials, we add the total number of times the number cube was rolled and the coin was flipped:
Total trials = 100 (rolls) + 100 (flips) = 200
Now, let's calculate the probability:
Probability = (Number of times rolling a 4 and landing heads) / Total trials
Probability = (28 + 44) / 200
Probability = 72 / 200
Probability = 0.36
Therefore, the probability of rolling a 4 on the number cube and the coin landing heads up is 0.36.
Winnie 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 18 2 25 3 12 4 28 5 7 6 10 Heads Tails 44 56Using Winnie's simulation, what is the probability of rolling a 4 on the number cube and the coin landing heads up?
