While shuffling a pack of 52 playing cards, 2 are accidentally dropped. Find the probability that the missing cards to be of different colours `26/51`.
Explanation:
We know that out of 52 playing cards 26 are of red and 26 are of black colour.
∴ P(both cards of different colour) = `26/50 xx 56/51 + 26/52 xx 26/51`
= `2 xx 26/52 xx 26/51`
= `26/51`
