5.1 /part I

Instructions

In this task, you will work with the introduction to probability. You will explain the basic concepts of probability and calculate the probability of a simple event. You should present the processes necessary to support the answers to the exercises and round the final results not the intermediate values that appear during the calculations to two decimal places, when necessary.

1. Determine the sample space of some identical marbles in an urn, which have been assigned numbers from 11 to 25.

2. Based on what you have learned about the values that a probability can acquire, determine:

a) the probability of an impossible event occurring =

b) the probability of an unavoidable event =

3. List one (1) example of a probability with a value of zero (0) and one (1) example of a probability with a value of one (1).

4. Would it be correct for a meteorologist to say that the probability of snow falling in the United States next December is ? He explains.

5. What does it mean if the result of a probability is too small, like 0.00003? Explain.

6. Which of the following values cannot be probabilities: 0, -1, 0.52, 2.1, 0.075, 1 / 2,0.9?

7. The following probabilities are given P (E1) = 0.20, P (E2) = 0.15, P (E3) = 0.40 and P (E4) = 0.25. Are these values legitimate? Explain

8. Determine the probability that a two (2) will be rolled when a die is rolled.

9. Determine the probability that an odd number will be rolled when rolling a die

10. Determine the probability that a number greater than three (3) will be rolled when rolling a die
