Answer

Explanation:

Step1: Use z - score table

Look up the value of 2.87 in the standard z - score table. The z - score table gives the cumulative probability $P(Z < z)$ for a standard normal random variable $Z$.

Step2: Find the probability

From the z - score table, when $z = 2.87$, $P(z<2.87)=0.9979$.

Answer:

D. 0.9979
