    Question
    HLPaper 2

    Athletes in a sports club have season's best times for the 100 m, which can be modelled by a normal distribution with mean μ=11.6\mu = 11.6μ=11.6 seconds and standard deviation σ=0.8\sigma = 0.8σ=0.8 seconds. To qualify for a particular event, an athlete must have a season's best time of under 11 seconds. An athlete from this club who has qualified for the event is selected at random. Find the probability that they have a season's best time of under 10.7 seconds.
