### Instruction: If the annual earnings per share has mean $8.6 and standard deviation $3.4, what is the chance that an observed EPS less than $5.5? Let's write a program.### Response: def solve():
    from scipy.stats import norm

    mean = 8.6
    std_dev = 3.4
    target_value = 5.5

    # Calculate the z-score
    z_score = (target_value - mean) / std_dev

    # Calculate the probability using the cumulative distribution function (CDF)
    probability = norm.cdf(z_score)

    return probability
print(solve())
