How do you input the mean and standard deviation into Desmos to define a normal distribution?

Use the normaldist function, specifying the mean and standard deviation as parameters (e.g., normaldist(μ, σ)).

Normal Distribution Calculations With Desmos Lesson Plan for Grade 11th Grade

I can use Desmos to calculate probabilities and percentiles for normal distributions.

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.
