Solution

given that P (no influence )=0.26

P(under influence = 0.74

So,

Probability of at least 1 has not driven a car under influence =1- P(both has driven under influence)

                                                                                       =1- 2C₂(0.74)²=0.4524(ans)

Probability of at least 1 has driven under influence =1- P(none has driven under influence)

                                                                         = 1- 2C₂(0.26)²= 0.9324(ans)
