COUNTING TECHNIQUES: PROBABILITY AND STATISTICS

The question used to answer the question above is:

The answer is as follows:

2. Write a MATLAB program to simulate the selection of two 20-item lists from a 500- item sample set, and demonstrate that the result matches the theoretical result calculated above. 1. A gene array used to determine which genes are being transcribed under certain experimental conditions contains 500 genes. A genetic algorithm is used to determine which promoters most likely resulted in the pattern of gene array data found in an experiment. This algorithm requires selection (randomly) of a list of 20 genes out of the 500 genes on the array. (No gene can appear more than once in a single list, and the order of the list is not important.) If two such 20-gene lists are selected randomly, what is the probability that they have at least one gene in common? . 31958. 2.
