I'm so sorry that this is probably a basic question. I am a student and have 0 prior experience with Mathematica or any sort of coding and I have looked at various resources trying to figure it out myself but still need help.

I currently have a list of values (called "ProbSurvMale" in my code)

{{0.958598}, {0.694663}, {0.118085}, {0.390693}, {0.762198}, \
{1.55629*10^-6}, {0.0292393}, {0.320323}, {0.139982}, {0.809311}, \
{0.0993175}, {0.961641}, {0.033014}, {0.833012}, {0.125618}, \
{0.971254}, {0.000109839}, {0.116335}, {0.00260359}, {0.0837473}}

I also have a RandomReal function.

draw := RandomReal[{0, 1}]

My code for the If statement is

Contest := If[draw < x, "live", "ded"]

I want to run the If statement for every value in the ProbSurvMale list. I don't know how to apply it to the list. I tried Contest @@@ ProbSurvMale, which gave me

{"live"[0.00206366], "live"[0.000243393], "live"[0.118085], 
 "live"[0.390693], "live"[0.0451756], "live"[0.44083], 
 "live"[0.851076], "live"[0.0000135539], "live"[1.28328*10^-6], 
 "live"[0.0362936], "live"[0.560129], "live"[0.0130393], 
 "live"[0.000628627], "live"[0.000651911], "live"[0.493252], 
 "live"[0.0116439], "live"[0.579737], "live"[0.0000690552], 
 "live"[0.0110516], "live"[0.0837473]}

and I tried Map[Contest, {ProbSurvMale}], which gave me

{"live"[{{0.00206366}, {0.000243393}, {0.118085}, {0.390693}, \
{0.0451756}, {0.44083}, {0.851076}, {0.0000135539}, {1.28328*10^-6}, \
{0.0362936}, {0.560129}, {0.0130393}, {0.000628627}, {0.000651911}, \
{0.493252}, {0.0116439}, {0.579737}, {0.0000690552}, {0.0110516}, \
{0.0837473}}]}

Also, "live" is a placeholder for now. I want the term to retain its original value if the If condition is true.

Any help would be greatly appreciated!

Contest[x_] := If[draw <x, "live", "ded"];
Map[Contest, ProbSurvMale, {-1}]

{{"live"}, {"live"}, {"ded"}, {"live"}, {"ded"}, {"ded"}, {"ded"}, {"ded"}, {"ded"}, {"live"}, {"ded"}, {"live"}, {"ded"}, {"ded"}, {"ded"}, {"live"}, {"ded"}, {"ded"}, {"ded"}, {"ded"}}

Contest @@@ ProbSurvMale

{"live", "live", "live", "ded", "live", "ded", "ded", "ded", "ded", "live", "ded", "live", "ded", "live", "ded", "live", "ded", "live", "ded", "ded"}
