A fair die is rolled four times. Find the probability that all four rolls show different numbers
tensa zangetsu [6.8K]

Number of such outcomes, in which each number is no less than the preceding number, will be equal to number of ways of selecting 4 numbers from 6, with replacement; without considering order!


Why?


Lets choose any such set of size 4, say {2, 1, 1, 3}. we can sort it to get a sequence {1,1,2,3} which is one of our desired outcomes. So each such sorted sequence corresponds to one selection of size 4, with replacement and without considering order.


Number of such selections will be equal to number of solutions of following equation:


x1 + x2 + x3 + x4 + x5 + x6 = 4


where:


x1: number of 1 in the selections


x2: number of 2s in the selection


.


.


x6: number of 6s in the selection


Number unique solutions of such equation = 9 choose 5 = 126


(For more details on this see : Unordered sampling with replacement )


Number of possible outcomes = 6^4 = 1296


Probability of favorable outcomes = 126/1296=7/72

A binomial distribution has p = 0.05 and n = 50. what is the mean of this distribution?
Kruka [31]

2.5 is the mean of this distribution.

What is the distribution's mean?

  • The expected value, commonly known as the mean of a statistical distribution with a continuous random variable, is calculated by integrating the product of the variable's probability as described by the distribution.
  • The lowercase Greek letter mu () stands for the expected value. A probability of 50% equals zero standard deviations, and the mean is in the middle of the normal distribution.

Given: p = 0.05 and n= 50

Mean of the binomial distribution = n×p = 50 × 0.05 = 2.5

Therefore, option a is the correct answer. Other options are incorrect because these are irrelevant.
