Before we find the total number of blocks 13+8+9+10=40 blocks


chance of having the green block 13+8+10/40
31/40=0.775 present as Take it easy

The probability that Shelly will choose a block that is not green is 0.775. This is calculated by finding the total number of blocks and the number of blocks that are not green. There are 31 blocks that are not green out of a total of 40 blocks.
