There is not enough information to answer the question sensibly. Is it implied that out of 200 students not one knew the answer to any one of the seven questions? And that all pupils had to make random choices for each question? Is that at all credible?
1/8 or 12.5%
What is the probability of getting a sum of 5 if the dice is tossed 120 times?
Prob(at least one 5 in 120 throws) = 1 - prob(no 5s in 120 throws)= 1 - (5/6)120= 0.999 999 999 69 = almost 1.
Prob(at least one 5 in 120 throws) = 1 - prob(no 5s in 120 throws)= 1 - (5/6)120= 0.999 999 999 69 = almost 1.

Why do the ads cost between 3.0 and 50 millonds for just on 30 secons ad?
well its a combination of factors, its the old problem of supply and demand, you have 100+million people watching the show, which means it is one of the BIGGEST prime time spots for any commercial to have, plus over the years commercials have become exceedingly more complex and wondrous, its to the point where everyone expects amazing commercials for the superbowl, and knowing this the companies that air it (NBC) can basically hold a bidding war for the air time, 3.5million for 30 seconds was for the time itself, the rest is wasted on development of the commercials themselves, i hope i helped
What certain types of jobs is probability used in?

-- the Casino industry
-- Medical trials
-- Public opinion surveying
-- the spectator side of professional sports
Standardising the observation ensures that the mean is 0 and the standard error is 1. Otherwise the plot could be located anywhere and be concentrated or spread out.
How likely something is, it is like chance. Not yes or no, but leaning more likely than not. The amount that something is bound to happen. The probability of rain tonight is good means, it will probably rain. The probability of the bookstore running out of books, is slim to none. It shouldn't.
the likeliness of something happening.
A playing card is dropped 3 times What is the probability of it landing face up all three times?
1/2 * 1/2 * 1/2 or 1/8
Why are there fifty-two cards in a pack?
If your question refers to the structure of the cards, there are four suits, each with 13 cards:
A,2,3,4,5,6,7,8,9,10,J,Q,K
If your question refers to why these cards were selected, the popular answer is that there are four suits for the four seasons and thirteen cards in each because there are thirteen weeks in a season. As you can see, the 52 cards correspond with the fact that a year has 52 weeks.
What is the probality of picking 23 of hearts in a deck of cards?

If you meant to ask about the probability of picking a 2 or a 3 of hearts, then the probability is 2 in 52, or 1 in 26, or about 0.03846.
