Answer:
112/125
Step-by-step explanation:
If we know all 25 are in at least one foreign language class then we can assume that exactly 4 of the 18 kids in French only take French to add up to 25 and this means that the 14 left take both classes. Now we can create three fractions for each case which are 7/25 (Spanish only) 4/25 (French only) and 14/25 (Both) and we can know say that if he goes down the route of getting a Spanish only as his first he needs one of the 18 other students the chances of this happening are 7/25 * 18/25 = 126/625 the same thing is done with the French only and we get 4/25 * 21/25 = 84/625 and then we have the possibility of just getting a student that does both which is 14/25 or 350/625. now we add them all together to get 560/625 which is simplified to 112/125.
Hope this helps please mark brainliest :)
Yes, I can show you how to solve that problem.
Please watch carefully and try to follow me.
I'll go slowly, and you must stop me if I do
anything that's not clear to you.
You said that <u> Rick + 15 = 100</u>
Subtract 15 from each
side of the equation: <em>Rick = 85
</em>
Isolate the w. Note the equal sign. What you do to one side, you do to the other.
First, multiply w to both sides
(V/w)w = 9(w)
V = 9w
Next, Isolate the w. Divide 9 to both sides
V(/9) = 9w(/9)
w = V/9
w = V/9 is your answer
hope this helps
