## R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r cars}
summary(cars)
```

## Including Plots

You can also embed plots, for example:

```{r pressure, echo=FALSE}
plot(pressure)
```

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.


# set seed

```{r}
set.seed(100)
```

# generate U(0,1)
```{r}
runif(100,0,1)
x1<-runif(100,0,1)
```

```{r}
plot(x1)
hist(x1)
```

# Binomial(1,0.5)
```{r}
rbinom(10,1,0.5)
x2<-rbinom(10,1,0.5)
plot(x2)
hist(x2)
```
