Answer:
b
Step-by-step explanation:
<span>All the information we have are the probabilities, and what we need is the lowest number: so let's choose the smallest probability among the numbers: 0.0065%, B 0.0037%,C 0.0108%,D 0.0029%, E 0.0145%. The smallest of the numbers is 0.0029% -it starts with two 00s and the number that follows, 2, is smaller than all there others - so the smallest probability is in option D - and the model would be the corresponding model (but we're missing some information here) </span>

Answer: (C) 8/30</h3>
===================================================
Explanation:
There are 5+3 = 8 people in choir and running club. I added the values in the overlapped region of the circles "choir" and "running club".
This is out of 2+5+6+7+3+4+3 = 30 people total.
Divide the two results to form the fraction 8/30
Ideally we should reduce to get 4/15, but your teacher has chosen not to reduce.
Subtract 6x from both sides to get:
2y=-6x+12
Then divide both sides by 2 to get:
y=-3x+6
They added it wrong. They added it like this:
When it shouldve been this:
They just added a place marker in all numbers below 100.
