Consider the experiment of tossing a fair coin three times and observing the number of heads that result (X = number of heads).
Crank

Answer:

The standard deviation for this distribution is 0.8660.

Step-by-step explanation:

For each coin toss, there are only two possible outcomes. Either it is heads, or it is tails. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

In this problem, we have that:

In each toss, heads or tails are equally as likely, since the coin is fair. So p = \frac{1}{2} = 0.5

Three throws, so n = 3

What is the standard deviation for this distribution?

\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{3*0.5*0.5} = 0.8660

The standard deviation for this distribution is 0.8660.

Each of 100 people receives a random item from a grocery store and assigns it a value between 1 (low) and 10 (high). They trade
belka [17]

Answer:

The answer is "After trading, the value would be higher because preferences are diverse".

Step-by-step explanation:

Every person receives a resulting in the possibility from either a grocery shop and gives a value of from 1 to 10. (high). Participants trade these goods with each other for items that prefer to receive randomly but instead assign a second value to the object that finishes after the trade is concluded (1 to 10 again). Its value would've been higher after trading because the total of those before trading choices is unique compared to an exchange sum.

Raul and his friends each way 1/20 of a ton are standing on a truck scale . The total weight shown by the scale is 3/4 of a ton
vivado [14]

Answer:

<em>15 people</em>

Step-by-step explanation:

since Raul and his friends each weigh 1/20 ton,

and the total weight reads 3/4 ton

The total number pf people on the scale will be:

<em>The total weight of Raul and his friends divided by their individual weight</em>

==> (3/4 ton) ÷ (1/20 ton)

= 3/4 X 20/1 = <em>15 people</em>
