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?
