Probabilities for Normal Distributions with Desmos Quick Tutorial
Guided Notes
3 key concepts
- 1
The weights of bags of mulch are normally distributed with a mean of 41.2 lbs and a standard deviation of 0.3 lbs.
- 2
To find the probability that a randomly selected bag of mulch weighs less than 41 lbs, select left for cumulative probability and enter 41 as the maximum.
- 3
To calculate the probability that a randomly selected bag of mulch weighs between 41 and 42 lbs, select inner probability with a minimum of 41 and a maximum of 42.
