Answer:
The probability that the proportion of airborne viruses in a sample of 662 viruses would be greater than 6%=0.00427
Step-by-step explanation:
We are given that
n=662
We have to find the probability that the proportion of airborne viruses in a sample of 662 viruses would be greater than 6%.
q=1-p=1-0.04=0.96
Now,
Hence, the probability that the proportion of airborne viruses in a sample of 662 viruses would be greater than 6%=0.00427
Answer:
4
Step-by-step explanation:
The ratio of green : pink = 32 : 56 = 4 : 7
After 7 pink are given away, then
ratio = ? : 49 = 4 : 7 ← ratio has to be the same
Using proportion
=
( cross- multiply )
7? = 196 ( divide both sides by 7 )
? = 28
Thus the ratio = 28 : 49 = 4 : 7
Thus 32 - 28 = 4 green should be given
