Probability

If by this you mean male and female then no. Although rare individuals with ambiguous characteristics do occur naturally in human and animal populations. Please see the wikipedia article entitled 'intersex' for more information.

No. Because standard deviation is simply the square root of the variance, their information content is exactly the same.

Prior probability is the probability that is assessed before reference is made to relevant observations.

For complex events, it is possible to calculate the probability of events, but often extremely difficult. In the given example, for an "average" person (that would need some definition to start with) you would need to know the probability of them scoring a basket without the blindfold - this can be found by observing a number of "average" people attempting a number of baskets and seeing how many are successful (the greater the number of observations, the better the accuracy of the [estimation of the] probability. Also, the effect of blindfolding them needs to be found - this is not so easy, but some measure could possibly be made - and then combining this effect and the probability found some estimation of the probability of the required event can be calculated.

Someone has analysed tennis scoring and given the probability of one of the players winning a point (which can be estimated fairly accurately through past observation) has calculated the probability of them winning the match; however, each match (and even a game within a match) can be affected by further factors (eg one player suffering a small injury) which modify the probability of winning a point, but a calculated probability can still be made.

They are observations with a low likelihood of occurrence. They may be called outliers but there is no agreed definition for outliers.

It is 28.73

Estimates of the mean are then more reliable.

The maximum likelihood estimate, possibly.

The answer will depend on what the 8 numbers on the spinner are!

It is not possible. There have never been half that number of people alive at any one time.

This calculation is a crude demonstration, among other things, that everyone is related, however distantly, to everyone else.

There are 5 possible answers. The question needs to be more specific.

The mathematical probability of getting heads is 0.5. 70 heads out of 100 tosses represents a probability of 0.7 which is 40% larger.

16.66... % of the time - if the die is fair. And the percentage is not affected by the number of times you roll it.

total outcome in single toss={H,T}

u want 1 head

probability of getting 1 head= 1/2=0.5

1/6 for each one

but for both it is 2/6
