If you'd estimate the numbers, it would be $3500÷700. Because if you look at the tenths place, if the number is higher than 5, than the first digit goes up.
$3500÷700=5
Im not very good at explaining.
The correct option is the first one. Independent events are exactly what you're asking for: the information you have on one event doesn't affect in any way the probability of the other.
A classic example is the roll of two dice: assume that you roll the first one and get a 4. Does this imply anything on the outcome of the second die? No, all events 1,2,3,4,5,6 are still equally distributed, no matter the result of the first die.
It’s the first one - 3x^2 - 3x+8 - 9/x+1
