so the answer is 1
Answer:
The required probability is, 0.78
Step-by-step explanation:
There are, (52 - 13) = 39 cards which are not spade
5 cards can be chosen from the deck of 52 cards in
ways
and out of these 5 choices, none of them will be spade in,
ways
So,
P(None of the chosen cards is spade)
= ![\frac {^{39}{C}_{5}}{^{52}{C}_{5}}](https://tex.z-dn.net/?f=%5Cfrac%20%7B%5E%7B39%7D%7BC%7D_%7B5%7D%7D%7B%5E%7B52%7D%7BC%7D_%7B5%7D%7D)
![\simeq 0.22](https://tex.z-dn.net/?f=%5Csimeq%200.22)
Hence,
P(out of these 5 choices, at least one card is spade)
![\simeq (1 - 0.22)](https://tex.z-dn.net/?f=%5Csimeq%20%281%20-%200.22%29)
= 0.78
