    the road user will have to wait for more than 4 seconds 17times

    Step-by-step explanation

    The red signal is for stop and the probability of it happening is 1/3 for the first time.

    For 50 times it will be (1/3) * 50 = 16.666667

    Hence the road user will have to wait for more than 4 seconds 17times
