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 56
Using Winnie's simulation, what is the probability of rolling a 4 on the number cube and the coin landing heads up? 16 over 100
72 over 100
1232 over 10000
2432 over 10000
To find the probability of rolling a 4 on the number cube and the coin landing heads up, we first need to calculate the total number of times the cube was rolled and the coin was flipped.
Total number of rolls = 18 + 25 + 12 + 28 + 7 + 10 = 100
Total number of coin flips = 44 + 56 = 100
Now, we need to find the number of times a 4 was rolled and heads were flipped.
Number of times rolling a 4 and heads = 28
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 28 / 100
Probability = 0.28
Converting this fraction to a common denominator of 100:
Probability = 28 over 100
Therefore, the probability of rolling a 4 on the number cube and the coin landing heads up is 28 over 100.
no
My apologies for the mistake. Let's reevaluate the probability calculation.
The probability of rolling a 4 on the number cube is 28/100.
The probability of the coin landing heads up is 44/100.
To find the probability of both events happening simultaneously, we need to multiply the individual probabilities together:
(28/100) * (44/100) = 1232/10000
Therefore, the probability of rolling a 4 on the number cube and the coin landing heads up is 1232/10000.
