It is 1/4.
The required probability is 1/8.
If the probability of an event will occur is p, then the probability that it will occur in n trials is pn.(That's p raised to the n power). So if you bet on 12 numbers, then (38-12=26) numbers are empty. The probability of the ball landing on one of these empty numbers is 26/38. So (26/38)^11 = 0.01538, which is about 1.538 % or a 1 in 65 chance.
No; if it is certain not to occur the probability is 0.
Theoretical probability is what should occur (what you think is going to occur) and experimental probability is what really occurs when you conduct an experiment.
It is 1/4.
Probability is the likelihood that something will occur. If you subtract it from 1, we get the likelihood (or probability) that it will not occur. If a coin is tossed and rolls heads 6 times, the (empirical) probability of obtaining a head is 6/10 or .6. 1-.6 =.4 is the empirical probability (or likelihood) of not getting a head.
Yes. It is a certain event. If a coin is tossed, a 'head or tail would roll' is a certain event and has probability 1.
The required probability is 1/8.
The probability that an event will occur plus the probability that it will not occur equals 1.
If the probability of an event will occur is p, then the probability that it will occur in n trials is pn.(That's p raised to the n power). So if you bet on 12 numbers, then (38-12=26) numbers are empty. The probability of the ball landing on one of these empty numbers is 26/38. So (26/38)^11 = 0.01538, which is about 1.538 % or a 1 in 65 chance.
These events are complementary. Let P(A) = probability event will occur. Then the probability it will not occur is: 1 - P(A).
The laws of probability predict what is likely to occur, not necessarily what will occur.
No; if it is certain not to occur the probability is 0.
Theoretical probability is what should occur (what you think is going to occur) and experimental probability is what really occurs when you conduct an experiment.
an impossible event has a probability of 0, it will never occur a certain event has a probability of 1, it will always occur
the probability a certain event will occur :-)
