Question

. In a shuffled 52-card deck, what is the probability that the top card is black or the bottom card is a heart?

Answer 1

Answer)

There are 26 black cards and 13 hearts

One card can be chosen from 26 in 26c1 ways = 26

And one card from 13 hearts can be chosen in 13c1 ways = 13

And 50 cards in between top and bottom can be arranged in 50! Ways

And total cards can be arranged in 52! Ways

Probability is given by favorable/total

= (26*13*50!)/(52!)

= 0.12745098039
