Pretty sure it’s..jk do your class
Answer:
Step-by-step explanation:
you have t as a total amount of the whole class.
f= did not pass and you place the total number next to it like this; f/t represents that group. You continue this in your workings.
f/t = probability failed.
p/t = probability passed
c/t = probability completed
dc/t = probability did not complete
and draw a tree.
The random would be either of these, we know there s a possibility of 1/4 but the odds stay central. We look for a new way after this data is converted as a fraction and show these fractions as your answer.
The answer is: -4/a^2 b^2
This question doesn't make sense.Are you sure you wrote it correctly?
I don't really understand what you're asking, but if you're asking the sum of 8 plus 10, it's 18. Sorry if I didn't help, you can try clarifying though :)
