Make a plot
Finally, let us construct a plot that shows the probability of a match by sample size, using the pbirthday function that we practiced using in the previous exercise.
This exercise is part of the course
Probability Puzzles in R
Exercise instructions
- Set the variable
room_sizesequal to the set of integers from 1 through 50. - Run the
pbirthdayfunction in ansapplycall with the vector of room sizes and store the result asmatch_probs. - Make a plot with room size on the x-axis and match probability on the y-axis, using the two variables that you created.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Define the vector of sample sizes
room_sizes <- ___
# Run the pbirthday function within sapply on the vector of sample sizes
match_probs <- sapply(___)
# Create the plot
plot(___ ~ ___)
