Each ream weighs 5 lb . so, reducing 10 lb means removing 2 reams from the 12. so, how do we arrange the 10 reams so that its easy to carry?
i thinks that 3 stacks will not work as it wont be a symmetric arrangement as 1 will be left out. So, 2 stacks of 5 each would be easy to carry. but the stacks should be placed in such a way that the lengths are parallel to each other and not in-line which would increase the length making it comparatively longer. its easier to hold a (2*8.5,11,2*5=17,11,17)compact box.
Answer:
There is a 14.71% probability of teacher picking all 3 girls.
Step-by-step explanation:
Initially, there are 18 students, of which 10 are girls. So there is a 10/18 = 5/9 probability that the first student chosen is a girl.
Now, since the first student chosen was a girl, there are 17 students, of which 9 are girls. So there is a 9/17 of the second student chosen being a girl.
Both students picked were girls. Now there are 16 students, of which 8 are girls. So there is a 8/16 = 1/2 probability of the third student chosen in this situation being a girl.
Probability of teacher picking all 3 girls?
We multiply these probabilities:
There is a 14.71% probability of teacher picking all 3 girls.
Floor seats because for every balcony seat you get 20 floor seats.
hope this helps :P
<span>5-(49/1-5)*2+9-3
= 5-(49-5)*2+ (9-3)
= 5 -44*2+ 6
= 5 -88+ 6
= -83+ 6
= -77
The final answer is -77~</span>
