Answer:
0.1965%
Step-by-step explanation:
Because 13/52 are the same suit, we find the probability of 5 cards of the same suit (without replacemennt).
13/52=0.25
12/51=0.235
11/50=0.22
10/49=0.204
9/48=0.188
*multiply sums*
=0.0004957
*multiply by 4 since there are 4 different suits*
=0.001965x100=~0.1965%
