Answer:
40/289
Step-by-step explanation:
We can see these two events are independent as Regina replaced marble after drawing one marble.
We can find possible outcomes by adding number of blue, red and yellow marbles.
possible outcomes= 4+3+10= 17
Let us find probability of getting a blue marble on first draw.

Now we will find probability of getting red marble.

We can find probability of getting a blue marble and then red marble by multiplying both probabilities.

The expression is a bit invalid. You can't add variables by variables.
Answer:
I think the answer is B.7070-(-7460)
I'm sorry if it was wrong..
The answer for that equation will be 0.375.
H= (2pier^2)/ 2pier all subtracted by s so the last equation from the picture.
Hope it helps!
