Comparing total winnings
Oops, it seems like you are losing money. Time to rethink and adapt your strategy! This will require some deeper analysis…
After a short brainstorm in your hotel's jacuzzi, you realize that a possible explanation might be that your skills in roulette are not as well developed as your skills in poker. So maybe your total gains in poker are higher (or >
) than in roulette.

Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Poker and roulette winnings from Monday to Friday:
poker_vector <- c(140, -50, 20, -120, 240)
roulette_vector <- c(-24, -50, 100, -350, 10)
days_vector <- c("Monday", "Tuesday", "Wednesday", "Thursday", "Friday")
names(poker_vector) <- days_vector
names(roulette_vector) <- days_vector
# Calculate total gains for poker and roulette
total_poker <-
total_roulette <-
# Check if you realized higher total gains in poker than in roulette
