1. There are 150 students in a college of whom 66 play

basketball, 45 play cricket and 42 play soccer, 27 play

exactly two of three sports & 3 play all of three sports,

How many of 150 play none of 3 sports?

30 is the correct choice.

Step-by-step explanation:

150 = {baseball} + {cricket} + {soccer} - {exactly 2 sports} - 2*{exactly 3 sports} + {none of the ports}

150 = 66 + 45 + 42 - 27 - 2*3 + {none of the ports}

--> {none of the ports} = 30

Best Regards!
