Probability is the chance that a given event will occur in an experiment. You can use probability to predict outcomes.
A coin contains one head and one tail, so the probability will be 1/2.
To predict how many times you may flip heads, multiply probability of flipping heads by the number of trials.
Probability (head) = 1/2
1/2 x 10 = 5
Prediction: about 5 times
You would expect to flip 5 heads in 10 tries.
Example:
Predict how many times you will spin the number 1 in 40 spins.
Probability (1) = 1/4
1/4 x 40 = 10
Prediction: about 10 times
You would expect to spin the number 1, 10 times in 40 tries.
