A) \[\frac{1}{26}\]
B) \[\frac{3}{26}\]
C) \[\frac{4}{13}\]
D) \[\frac{3}{13}\]
Correct Answer: C
Solution :
Probability that it is queen \[P(A)=\frac{4}{52}=\frac{1}{13}\] Probability that it is heart \[P(B)=\frac{13}{52}=\frac{1}{4}\] Probability that it is queen and heart \[P(A\cap B)=\frac{1}{52}\] \[\therefore \] P (Queen or heart) \[=P(A)+P(B)-P(A\cap B)\] \[=\frac{1}{13}+\frac{1}{4}-\frac{1}{52}\]\[=\frac{4+13-1}{52}\]\[=\frac{16}{52}=\frac{4}{13}\].
