Ответ:
The probability that none of the three shoppers purchased electronics is 0.528
Step-by-step explanation:
Completing missing parts of the question
Electronics - 18
Pet supplies - 25
Toys - 40
Office supplies - 12
Total = 95
The probability that none of the three shoppers purchased electronics is calculated as follows.
Electronics Shoppers = 18
Non electronic shoppers = 95 - 18 = 77
Probability without replacement;
Probability that the first shopper didn't buy electronics = 77/95
Probability that the second shopper didn't buy electronics = 76/94
Probability that the third shopper didn't buy electronics = 75/93
Multiplying these values gives us our result.
Probability = 77/95 * 76/94 * 75/93
Probability = 0.528483184625943
Probability = 0.528 --- approximated
Hence, the probability that none of the three shoppers purchased electronics is 0.528
