Please help with the following problem. Provide step by step solutions.

Questionnaire responses were examined for illness first occurring, or intensifying, after May 1, 1973. Of 78 different health questions asked, only 6 conditions showed sufficient numbers of positive responses (10 or more) to permit statistical analysis. These were rash, anxiety, tiredness, headache, numbness, and balance problems.

QUESTION: Assuming that none of the 78 conditions were truly associated with quarantine status (e.g., under the null hypothesis for every condition), what is the likelihood that the p-value for one condition would be equal to or less than 0.05

Please show calculations.
