What else can I help you with?
What is the probability that two heads will occur if a fair coin is tossed twice?
It is 1/4.
A coin is tossed 3times .determine P(EF)whereEHESD ON 3rd toss .Fhead occur on 1st two toss?
The required probability is 1/8.
There are 38 numbers on a roulette wheel and I bet 12 of them. What is the probability of not hitting one of my numbers on 11 consecutive spins?
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.
The probability that an event will occur is 0.2. what is the probability that the event will not occur?
The probability that an event will not occur is calculated by subtracting the probability of the event occurring from 1. Given that the probability of the event occurring is 0.2, the probability that it will not occur is 1 - 0.2 = 0.8. Thus, there is an 80% chance that the event will not occur.
Is the probability assigned to an event that is certain not to occur is 1.0?
No; if it is certain not to occur the probability is 0.
What is the probability that two heads will occur if a fair coin is tossed twice?
It is 1/4.
Probability is the what that something will or will not occur?
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.
An event that must occur has 1 for probability?
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.
A coin is tossed 3times .determine P(EF)whereEHESD ON 3rd toss .Fhead occur on 1st two toss?
The required probability is 1/8.
What is the probability of an event occurring to the probability that it will not occur?
The probability that an event will occur plus the probability that it will not occur equals 1.
There are 38 numbers on a roulette wheel and I bet 12 of them. What is the probability of not hitting one of my numbers on 11 consecutive spins?
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.
Probability of an event occurring to the probability that it won't occur?
These events are complementary. Let P(A) = probability event will occur. Then the probability it will not occur is: 1 - P(A).
Does Probability predict what will definitely occur?
The laws of probability predict what is likely to occur, not necessarily what will occur.
Is the probability assigned to an event that is certain not to occur is 1.0?
No; if it is certain not to occur the probability is 0.
What is experimental probability vs theoretical probability?
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.
Probability of an impossible event is?
an impossible event has a probability of 0, it will never occur a certain event has a probability of 1, it will always occur
What is theoretical probability?
the probability a certain event will occur :-)
