Answer:
2x^2+x-15
Step-by-step explanation:
6x-15+2x^2-5x
2x^2+x-15
Step-by-step explanation:
vol =πr²h
22/7×8×8×3
= 603.2
Make the circle closed and the > needs to be underlined
There are 7 marbles, including 3 green ones, so at the start, there is a 3/7 chance of getting a green marble.
Assuming you did get a green one, there are now 6 marbles left, with 2 blue marbles, so there is a 2/6 chance of taking a blue marble.
Given that both have to happen, you must multiply each probability, hence the total probability is 3/7 x 2/6, or a 1/7 chance.
Hope this helped
