Based on the experimental probability, predict the number of times that you will roll a 5 if you roll the number cube 300 times.
A. 15
B. 27
C. 48
D. 54
Based on the experimental probability, the likelihood of rolling a 5 can be calculated by dividing the frequency of rolling a 5 by the total number of rolls (50).
Likelihood of rolling a 5 = 9/50 = 0.18
To predict the number of times that a 5 will be rolled if the cube is rolled 300 times, we can multiply the likelihood by the total number of rolls:
Number of times to roll a 5 = 0.18 x 300 = 54
Therefore, the answer is D. 54.
Hey bot I have a question
You roll a number cube 20 times. The number 4 is rolled 8 times. What is the experimental probability of rolling a 4?
The experimental probability of rolling a 4 can be calculated by dividing the number of times a 4 is rolled (8) by the total number of rolls (20).
Experimental probability of rolling a 4 = 8/20
Simplifying this fraction, we get:
Experimental probability of rolling a 4 = 2/5
Therefore, the experimental probability of rolling a 4 is 2/5 or 0.4 (as a decimal or percentage).
bot what is 0.4 as a percentage
0.4 expressed as a percentage is 40%.
To predict the number of times you will roll a 5 if you roll the number cube 300 times, we can use the concept of experimental probability.
Experimental probability is calculated by dividing the number of times an event occurs by the total number of trials. In this case, we will divide the frequency of rolling a 5 by the total number of rolls (which is 50) to get the probability of rolling a 5 in a single roll.
Probability of rolling a 5 on a single roll = Frequency of rolling a 5 / Total number of rolls = 9 / 50 = 0.18
Now, to predict the number of times you will roll a 5 if you roll the number cube 300 times, we will multiply the probability by the total number of rolls.
Number of times rolling a 5 = Number of rolls × Probability of rolling a 5 = 300 × 0.18 = 54
Therefore, the predicted number of times that you will roll a 5 if you roll the number cube 300 times is 54.
The correct answer is D. 54.
