Hello everyone today. We have question according to the question even is find out which of the following is not real. For canceling discrete is three probability probability distribution. Now we can say we have given the following options and which of the option is that correct? We can tell about this weekend then the first option is the probability of the anti specific values between the zero and the one is inclusive. Then we can say in this is we can say this is the less than one and greater than zero. This is the inclusive case. But we tell about it. The discrete probability distribution, it is not the discrete probability distribution. Then we can see the option is the wrong answer. Now we go to the second option. The mean of the distribution is between the smallest and the largest value. Then this season also is not always to statement which is the sometimes sometimes this is always you can say the meal distribution is between the smallest. They can tell about the discrete probability distribution. Then we go to the third option then for the distribution distribution option is incorrect. Now we go to the third option, we can not at the standard division. We can then know that the standard aviation ballets formalizing equals the square root of variants and we know that the variance and under the square root they can say this is always the positive part and we get the output is also positive. So we can say that medication rains is always greater than zero because of this, the positive case and we can see this is that also equals to zero if case in case under the square root of zero to make it to get a zero value, but it is always positive. Always. Was it him? What? In the third option we can say the standard deviation is between the -12. It means it has contained the value of minus one minus 10.992 minus 0.1. These values are not comes from that. Then we can say this statement is not true. This statement is not true. Always. This statement is always the truth. So we can say the option sees the correct answer. Then we can say this is the correct answer of this question. Now we go to the fourth option. That distribution may be displayed using probability no, no, this is not a part of the concrete concerning the probability distribution some of the old abilities one, it is not always true In some cases the probability of the older one is not true. Then we can say the option C is the correct transfer of this question. I hope you listen to solution. Thank you
