    Step-by-step explanation:

    Given that the year is having only 365 days (not a leap year)

    P (anyday as birthday) = 1/365

    Any body will have a chance of having on Monday the birthday

    =52/365 (assuming 52 Mondays as given)

    Hence we can expect 365/52 = 7.019

    i. e. if 7.019 persons are present there will be a definite chance for any other person to share this birthday

    Hence atleast 8 people we need in a room so that you expect that there is going to be a shared birthday on a Monday of the year
