You roll a fair, four-sided die twice. Let the random variable X = "number of times rolled on the number 4," with x = 0, 1, 2.Which histogram shows the correct probability distribution based on the scenario above? (choose one of three graphs in image)

A bowl contains 24 pieces of fruit, 6 oranges and 18 apples.  Two pieces of fruit are randomly selected without replacement. The random variable X = # of apples selected.  Determine the probability distribution for the random variable X.

Let the random variable x represent the number of girls in a family of 3 children. Construct a table describing the probability distribution, then find the mean and SD. Is it unusual for a family of 3 children to consist of 3 girls

In the winter, guests who visit Yosemite National Park like to stay at an overnight lodge in the park 66 % of the time. Find the probability that among 7 guests surveyed exactly 5 guests like to stay at an overnight lodge in the park.P(x = 5)

Make a histogram of the probability distribution of X. Describe its shape.

Take a case of tossing of 20 coins. Draw a probability distribution of all the exhaustive events possible in the case. Use excel for calculations and plotting.

While gathering eggs one day, Lisa has 15 eggs when Liana has 20 eggs at the moment when they started throwing them at each other. If 10% of the eggs are rotten, use the Binomial Distribution to calculate the probability that Lisa was hit by 3 or fewer rotten eggs from Liana.

Gg.94.   According to Baseball Insider Magazine 25% of major league pitchers are left-handed. A recent report shows that 60% of left-handed pitcher undergo rotator cuff surgery, while 30% of right-handed pitchers undergo rotator cuff surgery. If a major league pitcher underwent rotator cuff surgery yesterday afternoon, what is the probability that this pitcher was right-handed and underwent rotator cuff surgery?
