There are 15 marbles in the bag. This gives us the probability of picking a red marble as 5/15, or 1/3. Because you replace the marble therefore making the probability the same each time, and as it's a logical 'and' operation, you multiply the probabilities like this:
(1/3)•(1/3)=(1/3)^2
Because (a/b)^c = a^c/b^c, P(two red marbles) = 1^2/3^2 = 1/9.
Qince the distribution is uniform, the expected temperature is the average: (15+35)/2=25
The 3rd choice is the right answer here
Hope this helps :)
Have a wonderful day !

Step-by-step explanation:
Tall Mountain is 8606.37 feet higher than Mt. Might. Let's replace the missing number with x.
Let's set up an equattion:
x = 20,738.5 + 8,606.37
Now let's solve the equation.
20,738.5 + 8,606.37 = 29,344.87
Add feet after the answer.
29,344.87
