3285 days.This is the answer.
If a light bulb consumes 600 per day, then you need to divide 2250 by 600. So it would be around 3.75 days
Your answer would be C. 27/190.
This is because the probability of choosing green as the first marble would be 9/20, as there are 20 marbles in total and 9 of those are green.
The probability of choosing a red marble as the second marble would be 6/19, as no red marbles would have been lost if green was picked first, but there would be one less marble in total.
The 'and' rule for probability, the one that is used to determine the probability of P(A) and P(B), is to multiply, so we need to do 9/20 × 6/19 = 54/380 = 27/190.
I hope this helps!
Yi forgot two factors of 63, which are 3 and 21.
This would make the greatest common factor 21.
