get a random number from a normal distribution with a mean of 0 and a standard deviation of 1 in go

To get a random number from a normal distribution with a mean of 0 and standard deviation of 1 in Go, we need to use the math/rand and math packages. We can generate a normal distribution by using the rand.NormFloat64() function, which returns a random float from a normal distribution with a mean of 0 and standard deviation of 1.

Here's an example code snippet:

main.go
package main

import (
    "fmt"
    "math/rand"
    "math"
)

func main() {
    // Seed the random number generator with the current time
    rand.Seed(time.Now().UnixNano())

    // Generate a random number from a normal distribution with mean 0 and standard deviation 1
    randomNum := rand.NormFloat64()

    // Scale the number to have mean 0 and standard deviation 1
    scaledNum := 1 + 0*randomNum

    // Output the results
    fmt.Println("Random number from a normal distribution with mean 0 and standard deviation 1:", scaledNum)
}

In this example, we first seed the random number generator with the current time to ensure that we get a different random number each time we run the program.

We then generate a random number from a normal distribution by calling rand.NormFloat64(). We don't need to specify the mean and standard deviation since they are both 0 and 1, respectively, by default.

Finally, we scale the random number to have a mean of 0 and standard deviation of 1 by multiplying by the desired standard deviation (1 in this case) and adding the desired mean (0 in this case).

The final output should be a random number from a normal distribution with mean 0 and standard deviation 1.
