Answer: B) 1/204 Explanation: Let A, B, C be the events of getting a white ball in first, second and third draw respectively, then   Required probability = PA∩B∩C  = PA PBA PCA∩B  Now, P(A) = Probability of drawing a white ball in first draw = 4/18 = 2/9 When  a white ball is drawn in the first draw there are 17 balls left in the urn, out of which 3 are white  ∴PBA=317  Since the ball drawn is not replaced, therefore after drawing a white ball in the second draw there are 16 balls left in the urn, out of which 2 are white.  ∴PCA∩B =216=18  Hence the required probability = 29×317×18=1204

Pokhran is a city and a municipality located in Jaisalmer district in the Indian State of Rajasthan. It is a remote location in the Thar desert region and served as the test site for India’s first underground nuclear weapon detonation.

It shot into the international limelight on 7th September 1974, when the then Indian Prime Minister Indira Gandhi verbally authorised scientists at the Bhabha Atomic Research Centre (BARC) at Trombay to detonate small and miniaturised nuclear device. Throughout its development, the device was formally called the Peaceful Nuclear Explosive (PNE) by Indian Government, but it was usually referred to as the Operation ‘Smiling Buddha’. On 11th May of 1998, 24th year after the first operation, the Atomic Energy Commission of India and the Defence Research and Development Organisation (DRDO) carried out the joint operation, known as Pokhran-ll. The AEC India detonated its four devices as part of the underground nuclear testing on Pokhran Test Range.
