Answer:
0.140625
Step-by-step explanation:
Given that multiple-choice questions each have four possible answers (a comma b comma c comma d ), one of which is correct. Assume that you guess the answers to three such questions.
Each question is independent of the other with constant probability
p = Prob for correct guess = 1/4 = 0.25
q = prob for wrong guess = 1-p = 0.75
Hence
, since each question is independent of the other
=
2(2y-10)+3y=1240
7y-20=1240
7y=1260
y=180
2x+3(180)=1240
2x+540=1240
2x=700
x=350
So they sold 350 food tickets and 180 ride tickets in total.
