Probability is the ratio of no. of possible outcomes to the maximum no. of outcomes .

If any event doesnt occurs ,then it is 0/N,where N=maximum no of outcomes .and that is 0 itself ,hence that is signified by zero ,or will at max, all the possible outcomes wil occur ,which means N/N that is denoted by 1.

Hence probabilty for the occurance for any event is between 0 and 1.

What is the probability of singing a number?

The probability, in my case, is zero.

What does it mean if the probability of an even number is 0?

If the probability of a event is zero, then the event cannot occur. Therefore, if the probability of an even number is zero, then the probability of an odd number is one.

Can probability be equal to zero?

A probability can be any number between 0 and 1. Zero simply means there is not a possibility of something occurring. One means it is absolutely certain to occur.

A radom number generator is used to select a number from 1 to 100 What is the probability of selecting the number 153?

The probability should be 0 (zero). 153 is not between 1 and 100. If you meant your number generator to return a number between 1 and 1000, the probability would be 1/1000 = .001 = .1%

Can the value of probability be less than zero?

No. Probability must be between 0 and 1.

How are negative integers measured?

Typically, negative numbers could be "measured" by the difference between the number and another number. The magnitude of a negative number is the distance from zero. Essentially, remove the minus sign, and you have the magnitude (also called absolute value) of the number.

If you roll a nine-sided die what is the probability you will roll a value greater than zero?

If zero is the number on one of the 9 sides, then the probability is 8/9 = 88.9% (rounded)If zero is not the number on any one of the 9 sides, then the probability is 100%.

What number can be used to describe the probability of an impossible event?

The probability of an impossible event is 0 (zero).

The denominator of probability can be?

It can be any number greater than zero.

What does a probability of 0 mean?

If an event has a probability of zero (0) that means that it cannot happen; it is completely impossible.If a number has a probability of zero, then it never occurs, no matter how many times you try.

What is the probability that the number 11 is even?

In base ten, and with no whacky assumptions, the probability that 11 is even is zero.

What does the probability of one mean?

A probability of one means that the outcome will definitely occur.Not asked, but answered for completeness sake - a probability of zero means that the outcome will definitely not occur. Probability always lies between zero and one, inclusive.
