In a survey of 280 college students, it is found that

67 like brussels sprouts,

93 like broccoli,

60 like cauliflower,

26 like both brussels sprouts and broccoli,

21 like both brussels sprouts and cauliflower,

20 like both broccoli and cauliflower, and

10 of the students like all three vegetables.

How many of the 280 college students do not like any of these three vegetables?
