Answer:
Probability of 100 managers being selected= 100C100*1100C800/1200C900
Probability of selecting just one manager = 1C100*1199C899/1200C900
Explanation:
Given 100 managers, 200 factory workers, 900 miscellaneous workers, and workers bring transferred 900
To find probability of 100 managers leaving given that probability = number of favorable outcomes/total number of outcomes
We use combination since order doesn't matter:
Combination formula= n!/r!(n-r)! Where n= total number of outcomes and r is number of outcome at one time and ! is factorial
Probability of 100 managers using nCr formula for each item = 100C100*1100C800/1200C900
Probability of 1 manager also applying nCr formula as above =1C100*1199C899/1200C900
It would be: (2/9)² = 4/81
In short, Your Answer would be Option A
Hope this helps!
Answer:
350
Step-by-step explanation:
40% of 250 is 100 (10% of 250 is 25 and 25 times 4 is 100)
250+100 is 350
(8/-4) / (-3/9)=
(8/-4) * (9/3)=
72/-12=
-6
