Generate 10000 numbers using RAND with probability

1. Given a sequence of U(0,1) random numbers, obtain and describe an algorithm that generate binary random numbers with the following point masses:

P{X = 0} = 0.3, P{X = 1} = 0.7

• Use MATLAB (0, ) random number generator “rand” to generate 10,000 random numbers with the above distribution.
• Compute the average value of the 10,000 numbers generated. Compare it with the theoretical mean.
• Give the percentages of the numbers generated that are equal to -1,0, and 1, respectively. Compare them with the point masses and make a comment.

@dlafont - what have you tried so far? Rather than copy and paste your homework assignment here (and like you did with https://www.mathworks.com/matlabcentral/answers/1684774-probability-calculation-for-bernoulli-trials?s_tid=srchtitle, please show us what you have tried and discuss where or why you are experiencing a problem.

This is my code but I keep getting the same error. Not sure how to go about setting up rand for 10,000 digits

[Torsten]

x = rand(0,10000)

You want a vector with 0 rows and 10000 columns ?

Ooops Fixed, still getting same error tho

Answer 1

[Geoff Hayes]

@dlafont - from the error, I think that you have a custom script called rand.m that is is conflicting with the MATLAB rand function. I recommend you delete the /MATLAB Drive/rand.m (or better, rename this file) and try again.

THANK U!!! It finally worked

Generate Random Sequences of length 10000

uniformly distributed over the interval 0 and0.5
