Detailed Solution

The total number of outcomes in a deck of playing cards is 52.
There are 26 red cards and 4 queens among which 2 are included in the red set, so we consider 2 queens in a deck of playing cards.
The Question Image of the random experiment as,
P(A)=Number of favorable outcomesTotal number of outcomes
The number of events getting cards neither a red card nor a queen is,
n(X) = 52 - 26 - 2
n(X)=24
So, the probability of getting cards neither a red card nor a queen is,
P(E)=n(X)n(S)
P(E)=2452
P(E)=613
The probability of getting neither a red card nor a queen is 613.
Hence, option 2 is the correct answer.
