Answer:
The probability a flower is AT LEAST 74 inches tall is 0.2525.
Step-by-step explanation:
Since the height is normally distributed, we can use normalcdf to solve for the probability. First, find the Z-score of 74, which is (x-mu)/standard deviation. Solving, Z=(74-72)/3, or 2/3. Using normalcdf(2/3, 10^99, 0, 1), we get the probability a flower is AT LEAST 74 inches tall to be 0.2525.
Note: If you're asking for the probability that a flower is equal to 74 inches tall, it would be 0, since individual values have no probability.
