Thank you !!

Dear Student Thank you for using Chegg !! Given that shuttle arrives in every 15 minutes Now total number of deciminutes available in a minute = 10 In 15 minutes total number of deci-minutes = 150 Now suitable cases when 4.8<= t <= 11.6 minutes Number of deciminutes = 59 Hence favourable outcomes = 59 Sample space = 150 Probability = 59 / 150 = 0.393333333 Solution
