These ratios are all equivalent to 18 : 4 :
9 : 2
4.5 : 1
6 : 4/3
36 : 8
18 trillion : 4 trillion
7 because 3 times 7 is equals 21
Answer:
2
Step-by-step explanation:
Given that:
Flawed bulbs = 4
Not flawed = 26

P(flawed) = flawed / total
P(flawed) = 4 / 30 = 0.1333333
If 15 is examined :
Expected number of flawed bulbs :
(4/30) * 15 = 2
