Well, the problem is that he does not replace the first marble after he draws it. Therefore, yes, he has a 2/12 probability of drawing a yellow marble first, but then he has a 4/11 probability of drawing a red marble second, not 4/12. This is because there are going to only be 11 marbles left in the bag after he draws the first marble and does not replace it.
The correct answer would be:
(2/12)(4/11)=8/132=4/66=2/33
Answer:
48
Step-by-step explanation:
the top shape is 6 by 6, which is 36
the bottom shape is 3 by 4, which is 12.
if you add the two areas, 12+36, you get 48. so the area of the entire shape is 48mi
Is = %
Of. 100
36. = x
60. 100
3600=60x
Divide by 60
x=60
So 36 is 60% of 60
Or 40% less than 60
