****Using R**** Calculate the entropy of the following cards not a computer person and everyone seems to get it but I have no idea what's happening. just need help writing codes for the following deck of cards outcomes

Shannon's Entropy Model (a) H(card) = 0.00 (b) H(card) = 0.81 (c) H(card) = 1.00 (d) H(card) = 1.50 (e) H(card) = 1.58 (f) H(card) = 3.58 Figure: The entropy of different sets of playing cards measured in bits.
