2. Two fair coins are tossed, and the following events are defined:

A: {Observe at least one head}

B: {Observe exactly one head}

a. State the sample points and write down the sample space. Which sample points are in A? B?

b. Draw a Venn diagram for the experiment, showing events A and B.

c. Calculate .

d. Use the formula for conditional probability to calculate Verify your answer by inspecting the Venn diagram and using the concept of reduced sample spaces. Explain your answer in words using the concept of reduced sample spaces and referring to the Venn diagram.

A random experiment was conducted where Person A tossed four coins and recorded the number of “heads”. Person B rolled two dice and recorded the smaller number out of the two dice. Answer the questions (either by direct computation or using simulations; use 10000 long columns). I) Which of the two persons (A or B) is more likely to get the number “3”? (6.66 points) a. Person A b. Person B c. Both persons have very similar probability of obtaining...

Two fair die are tossed, and the uppermost face of each die is observed. The following events are defined from this random experiment: AA represent the event the uppermost faces sum to five BB represent the event that the product of the uppermost faces is four. For example, die1*die2 = 4 CC represent the event that the absolute difference between the uppermost faces is 1. For example, |die1−die2|=1|die1−die2|=1 Part (a) Find the probability that the uppermost faces do not sum...
