A British passenger ship, sank after colliding with an iceberg. Here is data from the 2201 passengers on board, by cabin class. If we randomly select a passenger who survived give the probability in fraction to the below. a. P(Crew)

b. P(Survived and 3rd class)

C P(did not survive given they were in 2nd class)

d P (crew given they survivied)

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

answear:

a

step-by-step explanation: a

i need the options

step-by-step explanation:

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
