He sold all general admission tickets

Can prove using simultaneous equations

50x + 60y = $1050
x + y = 21 => y = 21-x

50x + 60(21-x) = 1050
50x + 1260 - 60x = 1050
-10x = 1050 - 1260
-10x = -210
x = -210/-10
x = 21

x + y = 21
21 + y = 21
y=0

Since he sold 21 general admission tickets and no VIP tickets

A chemical plant has an emergency alarm system. When an emergency situation exists, the alarm sounds with probability 0.95. When
Katen [24]

Answer:

the probability that a real emergency situation exists is 0.16 (16%)

Step-by-step explanation:

defining the event A= the alarm sounds ,we have

P(A)= probability that an emergency situation exists * probability that the alarm sounds given that an emergency situation exists + probability that a emergency situation does not exist * probability that the alarm sounds given that an emergency situation does not exist = 0.004* 0.95+ 0.996 * 0.02 = 0.02372

then if we use the theorem of Bayes for conditional probability and define the event E= a emergency situation exists , then

P(E/A)= P(E∩A)/P(A)= 0.004* 0.95/0.02372 =0.16 (16%)

where

P(E∩A)= probability that an emergency situation exists and the alarm sounds

P(E/A) =  probability that an emergency situation exists given that the alarm has sounded
