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.

Exercise instructions

  • Set the variable room_sizes equal to the set of integers from 1 through 50.
  • Run the pbirthday function in an sapply call with the vector of room sizes and store the result as match_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(___)
