Number of first class passengers = 325
Number of surviving passengers that took first class = 203
The probability that a passenger survived given that they took taking first class is
number of surviving passengers in first class/number of first class passengers. Thus, the probability is 203/325
Answer:
2:1
Step-by-step explanation:
2:3=1:3
as product of extremes = product of means
(2)(3):(1)(3)
6:3

Answer:
13r-13n
Step-by-step explanation:
just add 9r+6r get 15r then subtract it by 2r then you get 13r and you can't subtract unlike terms
9a - c Replace a with -7 and c with 6
9(-7) - 6 Multiply 9 by -7
-63 - 6 Subtract
-69
