A sample space consists of 4 simple events: A,B,C,D. Which events compromise the complement of A? Can the sample space be viewed as having two events, A and Ac ?

d) Ana tosses a 50p coin twice. What’s the probability she’ll get two heads?

You flip five coins and tally up the number of heads and tails. (You do not record the individual coin tosses.) a.) Describe the elements of the sample space in this experiment. (There should be 6.) b.) Let A be the event "a majority of the coins landed heads". List the elements of A. c.) Give an example of an event B in this experiment which is disjoint from A.

In a sales effectiveness seminar, a group of sales representatives tried two approaches to selling a customer a new automobile: the aggressive approach and the passive approach. For 1160 customers, the following record was kept:   Sale No Sale Row Total Aggressive 260 320 580 Passive 466 114 580 Column Total 726 434 1160 Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for events: A = aggressive approach, Pa = passive approach, S = sale, N = no sale. So, P(A) is the probability that an aggressive approach was used, and so on. 1. Compute P(N) and P(N | A). (Enter your answers as fractions.) P(N) =  P(N | A) =    2. Are the events N = no sale and A aggressive approach independent? Explain.   a. No. The two events cannot occur together. b.Yes. The two events can occur together.     c. No. P(N) ≠ P(N | A). d. Yes. P(N) = P(N | A). 3. Compute P(A or S). (Enter your answer as a fraction.)   P(A or S) =

The sample space listing the eight simple events that are possible when a couple has three children is​ {bbb, bbg,​ bgb, bgg,​ gbb, gbg,​ ggb, ggg}. After identifying the sample space for a couple having four​ children, find the probability of getting onegirland threeboys (in any order).   A. Identify the sample space for a couple having four children. ? (Use a comma to separate answers as​ needed.) B. Find the probability of getting one girl and three boys (in any order)? ​(Typean integer or a decimal. Do not​ round.)

There are 11 players on a baseball team, all with roughly equal athletic ability. The coach has decided to choose the players who will play the four infield positions (first base, second base, third base, and shortstop) randomly. Tori and Brittany are on a team. Determine the probability of Tori and Brittany being chosen to play in the infield
