Mikel runs his own business — he takes small groups of tourists on day-long tours of the city where he lives. He'll take up to

4

people at a time on a tour.

Mikel tracked how many people came on his tour in the last

200

days:

# of people	$0$ ‍	$1$ ‍	$2$ ‍	$3$ ‍	$4$ ‍
Frequency	$6$ ‍	$14$ ‍	$78$ ‍	$30$ ‍	$72$ ‍

Based on these results, which graph represents an approximate probability distribution of the number of people on a random tour?
