In a school of 330 students, 85 of them are in the drama club, 200 of them are in a sports team and 60 students do drama and sports. find the probability that a student chosen at random isn’t in the drama club or in a sports team.

7/22

Step-by-step explanation:

330 students total

200 - 60 = 140  is entered into Drama Club

60 in intersect for both

85-60 = 25 for Drama

25+60+140 = 225/330 do both sport and drama

330-225 = 105 = 105/330 do not do any sports or drama

105 is put in the outer box.

105/330 can be simplified by choice =21/66 = 7/22

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
