Answer:

Option D

Step-by-step explanation:

From the spinner we see there are 5 colours in there.

These are;

Green, Yellow, Red, Purple, Blue.

This means that when it is spinned, there's possibility of getting only one colour per spin.

Since she tosses a coin as well for each spin, there's a possibility of getting either a tail or head per spin.

This means, all possible outcomes will be 5 × 2 = 10 outcomes.

With each colour possibly showing up with either tail or head.

Correct answer is Option D as it has 10 possible outcomes in the correct order.

Korolek [52]

Answer:

0.509

Step-by-step explanation:

Given that a random sample of 1016 adults in a certain large country was asked "Do you pretty much think televisions are a necessity or a luxury you could do without?"

Of the 1016 adults surveyed, 517 indicated that televisions are a luxury they could do without.

To find out the point estimate of population proportion of adults in the country who believe that televisions are a luxury they could do without.

We find that point estimate is nothing but sample proportion

Sample proportion = favourably voters/total people surveyed

= $\frac{517}{1016} \\=0.5088\\=0.509$
