Answer:

Probability that he or she has no desire in skiing lessons is 57/80

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

Probability he or she has interest in skiing lessons is 115/400

Probability he or she has no interest in skiing lessons is 1 - (115/400) = 285/400 = 57/80
