For a standard normal distribution, find:

P(z < -2)
Express the probability as a decimal rounded to 4 decimal places.

To find P(z < -2) for a standard normal distribution, we need to calculate the area under the curve to the left of -2.

Using a z-table or a standard normal distribution calculator, we can find that the area to the left of -2 is 0.0228.

Therefore, the probability P(z < -2) is 0.0228 (rounded to 4 decimal places).
