Answer:
3.924×10∧-9
Step-by-step explanation:
Royal flush contains five cards and it's probability is 0.3924%≈0.003924
Straight contain five cards and it's probability is 0.0001%≈0.000001
The probability including straight and royal flushes will be 0.003924×0.000001≈3.924×10∧-9
6x - 3x^2 + 2x^2 -2x = 5x^2 + 15x
4x -x^2 = 5x^2 + 15x
-11x - 6x^2 = 0
-6x^2 - 11x = 0
use the quadratic formula
(-b±√(b²-4ac))/(2a)
