How many dice are in a box of dice?
A box contain 4 green and 2 blue dice. Three dice are chosen one after the other. Determine the values of the random variable G representing the number of green dice. 7. A Random Variables can either be Discrete or Continuous. 8.
What is the sum of two dice rolled together?
There are 36 possible outcomes of the additive dice roll. The way to roll a sum of 9 is 6 (and vice versa) and 3 or 5 and 4 (and vice versa). This is possible 4 of the 36 times, giving a probability the sum of the two dice rolled of 4/36 or 1/9.
How many ways can the dice fall to get 12?
There are 36 ways the dice can fall. There is 1 way to get a 12 (6 + 6), there are 2 ways to get 11 (5 + 6 and 6 + 5), and 3 ways to get 10. Therefore P(getting greater than 9) = P(getting 10) + P(getting 11) + P(getting 12) = 3/36 + 2/36 + 1/36 = 1/6.
How many red and blue chips are in a box?
A box contains 4 red and 2 blue chips. A chip is drawn at random and then replaced. A second chip is then drawn at random. a) Show all the possible outcomes using a probability tree diagram.
What is the probability of each value of a discrete random variable?
The probability of each value of a discrete random variable is between 0 and 1 inclusive. 0 ≤ P (x) ≤ 1 b. The sum of all the probabilities is 1. ∑ P (x) = 1 11. Example 1 Consider the following table x 0 1 2 3 P (x) 0.2 0.3 0.3 0.2
