For one toss of a certain coin, the probability that the outcome is heads is 0.6. If this coin is tossed 5 times, which of the f

pishuonlain [190]

Answer:

The probability is 0.33696

Step-by-step explanation:

The probability that the outcome will be heads x times is calculated using the following equation:

$P(x) = nCx*p^{x} *(1-p)^{n-x}$

nCx is calculated as:

$nCx=\frac{n!}{x!(n-x)!}$

This apply for variables that follows a binomial distribution. In which we have n independent and identical events with two possibles results: success and fail with a probability p and 1-p respectively.

So, In this case, n is equal to 5, and p is equal to 0.6 because we are going to call success the event in which the outcome of the coin is head.

Then, the probability that the outcome will be heads at least 4 times is calculated as:

P = P(4) + P(5)

Where P(4) is:

$P(4) = 5C4*0.6^{4} *(1-0.6)^{5-4}$

P(4)=0.2592

And P(5) is:

$P(5) = 5C5*0.6^{5} *(1-0.6)^{5-5}$

P(4)=0.07776

Finally, the probability is:

P = 0.2592 + 0.07776

P = 0.33696

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they spend on soc

Rasek [7]

Hi there!

Part A: Those groups of points that are circled and labeled A are called a correlation. In this case, the group of points represent negative correlation. The point that is labelled B is called an outlier, because it falls outside of the range of the other points. Point B may have been present like that, because while a person may spend a lot of time on social media, they might have understood the information very fast, or maybe they studied a bit on a different occasion.

Part B: Going back to part A, the graph represents a negative correlation. In this case, the more time spent on social media, the lower the test scores.
