    (i) 90%

    (ii) 10%

    Step-by-step explanation:

    Given the data as;

    Weather condition on-time Delayed Total

    Sunny 167 3 170

    Cloudy 115 5 120

    Rainy 40 15 55

    Snow 8 12 20

    Total 330 35 365

    The marginal distribution of arrival status in percentages = arrival status total/total sum * 100

    (i) on-time = 330/365 * 100 = 90.42 = 90%

    (ii) Delayed = 35/365 * 100 = 9.58 = 10%
