    Answer:.1 (0.9^3)

    Step-by-step explanation:

    We are given the following information:

    We treat left banded as a success.

    P (left handed) = 10% = 0.1

    Then the number of attendees follows a geometric distribution, where

    P (X=x) = p (1-p) ^x-1

    where x is the number of trails to get first success.

    Now, we are given x = 4

    =.1 (.9) ^3
