Likely something is to occur, or how likely something is true.
and . 0 indicates
Certainty.
The probability of an event is:
Formula
The number of ways the event can happen / The number of possible outcomes.
Probability = # of Ways / OutcomesWhen tossing a coin, there are two possible outcomes:
Formula
1/2 = 0.5Formula
1/2 = 0.5
P(A) - The ProbabilityA is often written as P(A). When tossing two coins, there are 4 possible outcomes:
Formula
Heads + Heads
1/4 = 0.25
Tails + Tails
1/4 = 0.25
Heads + Tails
1/4 = 0.25
Tails + Heads
1/4 = 0.25When throwing a dice, there are 6 possible outcomes:
Formula
1/6 = 0.166666Formula
1/6 = 0.166666Formula
1/6 = 0.166666Formula
1/6 = 0.166666Formula
1/6 = 0.166666Formula
1/6 = 0.166666The possibility of throwing 3 fours at the same time is
Formula
(1/6)(Lands on 4 to the power of 3):
let p = Math.pow(1/6, 3);The possibility of throwing 3 likes at the same time is 6 times larger:
Formula
(lands on 1) + (Lands on 2) + ... + (Lands on 6)let p = Math.pow(1/6, 3) * 6;6 Balls I have 6 balls in a bag: 3 reds, 2 are green, and 1 is blue. Blindfolded. What is the probability that I pick a green one?
