  1. Answer:

    [tex]\huge\bold{\textbf{\textsf{{\color{Black}{αɴѕωєя}}}}}[/tex]

    Let the event wherein 2 students having the same birthday be E

    Given, P(E) = 0.992

    We know,

    P(E)+P(not E) = 1

    Or, P(not E) = 1–0.992 = 0.008

    ∴ The probability that the 2 students have the same birthday is 0.008
