Ms. Bova flips a coin 50 times. What is the theoretical probability that she flips heads?
P(flipping heads) = 25/50 = 50%
What was the experimental probability of spinning Orange?
Green: 25
Yellow: 60
Orange: 15
Pink: 50
P(spinning orange) = 15/150 = 1/10 = 10%
At a school assembly 3 out of the first 10 students were wearing spirit wear. Based on this information, if 400 students were at the assembly, then how many students could be expected to be wearing spirit wear?
120
Is this theoretical or experimental probability? Why?
I rolled two six sided cubes 36 times and rolled a sum of 6 three times.
Experimental probability. This is an experiment where the outcomes were observed after 36 trials.
What is the likelihood or flipping green on a standard quarter
impossible
What is theoretical probability?
Theoretical probability is based on what is expected to happen.
define experimental probability
The probability that actually occurs
A box of 30 batteries is checked and two are defective. Based on these results, how many can be predicted to be defective in a box of 120?
8
Is this theoretical or experimental probability? Why?
The probability of getting heads when flipping a coin is 50%.
Theoretical probability. The outcomes of flipping a coin is heads or tails, there is an even chance of flipping heads as there is to tails.
Determine the likelihood if an event has a 0.4 chance or happening.
0.4=40% so unlikely
