Total outcomes: 52- 1% chance of any card
Outcomes for each type of card(heart, diamond,spades,cloves): 4 -25%
hope this helps
Step 1: Simplify both sides of the equation.
Step 2: Subtract 6x from both sides.
- 65x²+390x+585−6x=6x−6x
- 65x²+384x+585=0
For this equation: a=65, b=384, c=585
Step 3: Use quadratic formula with a=65, b=384, c=585
- x=−b±√b2−4ac/2a
- x=−(384)±√(384)2−4(65)(585)/
- 2(65)
- x=−384±√−4644/130
Therefore, There are no real solutions.
$13.68 because you do [.18+.06=.24] [18•.24=4.32] [18-4.32=13.68]
