Answer:
6 years
Step-by-step explanation:
1.75% of 1,200 = 21
so 1 year= 21
21+21= 42 2 years
42+21=63 3 years
63+21=84 4 years
81+21=105 5 years
105+21=126 6 years
Or you can do
21x6=126 so it has to equal 6 years
3 are expected to have the condition.
The expected value is the found by multiplying the probability by the number in the sample:
(1/200)×600
= (1/200)×(600/1)
= (1×600)/(200×1)
= 600/200 = 3
