Answer:
1/18
Step-by-step explanation:
there are 12 marbles in the bag
P(choose red) = 2/12 = 1/6
P(choose blue after replacement) = 4/12 = 1/3
P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18
3/4 is greater
hope it helps

Answer:
Step-by-step explanation:
r=(2,-3,0) + t (1,0,-1)
r=(2+t, -3+0t,0+(-t))
x(t)=2+t
x(t)=t+2
y(t)=0t-3
y(t)=-3
z(t)=0+(-t)=-t
z(t)=0-t
z(t)=-t
