- 4c1 *4c1 *4c1/52c1 *52 *c1 *52c1
1/13 1/13 1/13=1/13^3 - 12 years agoHelpfull: Yes(6) No(27)
- {(4c1*4c1*4c1)3!}/52c3.
3! is required as KQJ can also be suffled. - 10 years agoHelpfull: Yes(2) No(1)
- 4C*4C1*4C1/52C3
16/5525 - 10 years agoHelpfull: Yes(1) No(1)
- no of sample space= (4c1 * 4c1 * 4c1 )
=64
total sample space =( 52c3)
probability of drawing three card (k,q,j) = 64 / 52c3
=16/ 5525 - 9 years agoHelpfull: Yes(1) No(0)
- [(4c1/52)*(4c1/51)*(4c1/52)]*3!=16/5525
- 10 years agoHelpfull: Yes(0) No(2)
