Answer:

The probability is;

0.0000003645

Step-by-step explanation:

The probability of packages being early p is 90% = 0.9

The probability of packages being late q will be 1-p = 1-0.9 = 0.1

So the probability of 2 out of 10 random late will be subject to Bernoulli approximation of the Binomial theorem

That will be;

P(X = 2) = 10 C 2 0.9^2 0.1^8

= 0.0000003645

B. the republican definitely defeated the democrats

C. the republican defeated the democrats with probability of 0.60

D. It is not possible to predict the winner because less than 1% of the voters were in the sample

Answer: Option D

Step-by-step explanation:

The result of this election cannot be predicted accurately as only 1000 voters out of 3,000,000 were sampled.

To get a good sample, the sample must be at least 10% of the total population and be a representative of the population but in this context, the sample is even less than 1% (30,000). Thus, the prediction might be inaccurate...
