Answer:

Step-by-step explanation:

No of ways in which 5 cards are chosen is N=^{52}C_5

No of ways in which at most  4 cards are spades N_0=Total ways-5 spades

=^{52}C_5-^{13}C_5

Probability that at most 4 cards are spade P=\frac{N_0}{N}

P=\frac{^{52}C_5-^{13}C_5}{^{52}C_5}

P=\frac{2598960-1287}{2598960}

P=\frac{2597673}{2598960}=0.9995
