Solution

The correct option is B 250
There are four kings in a pack of 52 cards. If 2 cards are selected and both are kings, remaining cards will be 50 out of which 2 will be kings.

52 पत्तों के एक पैकेट में चार राजा होते हैं। यदि 2 पत्तों को चुना जाता है और दोनों राजा हैं, तो 50 पत्ते शेष होंगे जिनमें से 2 राजा होंगे।
