We know that
g=3
r=2
b=5
total marbies=g+r+b------> 3+2+5----> 10
a) <span>probability that the first marble is red
P(red)=r/total marbies------------> 2/10-----> 1/5
b) </span><span>probability that the second marble is blue
in this case total marbles-------> 9
P(blue)=b/total marbles----------> 5/9
c) </span><span>the probability that the first marble is red and the second is blue
(1/5)*(5/9)=1/9
the answer is
1/9</span>

Answer:
L=2(e+w)h
Step-by-step explanation:
I would interpret it like this L=(2e+2w)h
Factor out 2 to get L=2(e+w)h
Is there more to the question because this is just giving information for the formula.
