Answer:
2/8
Step-by-step explanation:
There are 2 green marbles.
In all, there are 8 marbles.
So, the probability is 2/8.
75.
Explanation: from 3 to 12, you add 9, and then double the 12 to get to 24, and then add 9 again to get to 33, and double it to get 66, so the pattern is to add 9 and then double.
2•10+5•3
10•3
35/30*5 ( do it on both sides )
you'll get 7/6 or 1 1/6
