In a dice game a pair of dice were thrown 180 times.
The event "seven'" occurred on 38 of those times. If these dice are
fair the probability of "seven"' is one-sixth. If they are loaded
the probability is higher.
(a) is the probability of "seven" what it should be if the dice
were fair? use a one-tailed test.
(b) find a 95% confidence interval for p ("seven") using the large
sample approximation.

1.) Two regular (six-sided) dice are thrown together. Use a tree
diagram to find the probability that one number is even and the
other is odd.
2.) The probability that January 1st of a randomly selected year
falls on a Monday is 1/7. The probability that January 1st and
January 8th of a randomly selected year both fall on a Monday is:
a.) 1/49 b.) 0 c.) 1 d.) 1/7 e.) 2/7
3.) In a group of 20 adults, there...

Suppose you’re playing a dice game in which two 6-sided dice are
thrown, and players win when the sum of the values appearing on the
dice is at least 7. In the last 100 games, you’ve noticed that
players have won 95 times. Do you have any reason to believe that
the dice are unfairly weighted using the central limit theorem? I
have understood up to getting z=7.434. But how do you know to find
P(z>7.434) and not use P(x<7.434)....

5.) Assume 365 days in the year and that people's birthdays are
randomly distributed throughout the year. With 16 people in the
room, what is the probability that at least 2 have the same
birthday? How many people are required so that the probability is
at least 50%?
6.) A factory has 3 machines (A, B,&C) A makes 20% of the
parts produced by the factory, B makes 30% of the parts and C makes
50% of the parts. 6%...

The likelihood of two fraudulent dice coming in pairs is six
times the likelihood of a single coming. The opposite faces of
these dice are painted in for the same color, in three color. Both
dice are painted 1 to 6 red, 2 to 5 green and 3 to 4 blue colors.
Two dice are being thrown together. The X-rassal variable is 0, if
is the same color as the colors on the faces on top. The X-rassal
variable is...

(a) Let (a, b, c) denote the result of throwing three dice of
colours, amber, blue and crimson, respectively., e.g., (1, 5, 3)
represents throwing amber dice =1, blue dice = 5, crimson dice = 3.
What is the probability of throwing these three dice such that the
(a, b, c) satisfy the equation b 2 − 4ac ≥ 0? [7 marks]
(b) From a survey to assess the attitude of students in their
study, 80% of them are highly...
