If we toss a fair coin, what is the probability that a tail will show up?
Event: 10 times, 29 people, landed on tails 150 times

When you toss a coin there are only 2 possible outcomes: a Head or a Tail
So the options for tossing a tail are 1 out of 2.

P(tail) = 1/2 = 50%
P(event) = 150/290 = 51.7%

"And"= multiply
"Or"= add

Theoretical Probability

Theoretical probabiliity is the likelihood that an event will happen.

P= n(e)/n(s)

Expiremental Probability

P(E)= R/N

Expiremental probability is the probability of an event and is the ratio of the number of times the event occurs to the total number of trials.

Probability is the measurement of how probable an event is.

Probability is determined by calculating the theoretical and expiremental probability of a given event.
