The answer is 2/90
Multiply 2/10 by 1/9
This is because the first time there are 2 green marbles and ten marbles total but the second time he had already taken out a green marble so there is only 1 green marble left and 9 marbles total.
Hope this helps :)
The clock breaks down to a different number sequence 2 B .5 it would be half past the hour 15 minutes past the hour would be 1 / 4 or .25
This question is really confusing.
z score = (1300-1700)/75
z score = -400/75 = -5.33
I would say b makes the most sense.
Hopes this helps!!Good luck!!
