Step-by-step explanation:
Urn U1: 3 red and 2 yellow marbles, in total 5 marbles.
The probability to select red marble is
Urn U2: 3 red and 7 yellow marbles, in total 10 marbles.
The probability to select red marble is
Urn U1: 1 red and 4 yellow marbles, in total 5 marbles.
The probability to select red marble is

Thus, the probability that the marble is red is
The volume of a pyramid is:
You need the height for this. You are given the hypotenuse of a triangle, and the base of that triangle is half of 42 if you can see that. So, let's solve for the height using pythagorean theorem:
Solve for h:
Now you have all the information, let's just plug everything in:
So, your volume is 597.33 cm³. Hope everything makes sense. hmy if something doesn't.
