Answer:
The answer is D
Step-by-step explanation:
because with each simulation, as the number of trials increase, the experimental probability gets closer and closer to the theoretical probability of
1
4
. The law of large numbers indicates that if an event of probability p is observed repeatedly during independent repetitions, the ratio of the observed frequency of that event to the total number of repetitions approaches p as the number of repetitions becomes arbitrarily large.
Jill is going to conduct three simulations of spinning a fair spinner (four sections of different colors--red, blue, yellow, and green). So, the probability of spinning a red is 2/5
Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.
Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).
Given the following information
Jill is going to conduct three simulations of spinning a fair spinner (four sections of different colors--red, blue, yellow, and green).
In the first simulation, she will spin the spinner 40 times,
the second simulation she will spin the spinner 80 times
for the third simulation, she will spin the spinner 120 times.
Total number of spin = 30 spin
The number of times it lands on red = 12 times
Pr(spinning a red) = 12/30
Pr(spinning a red) = 2/5
Hence the probability of spinning a red is 2/5
