Question

Jackie has a bag that contains the following tiles.SPELLJackie takes a tile from the bag without looking. Then she puts the tile back in the bag. Next, she takes a tile from the bag again without looking. Considerthe following eventsLF: She takes L first.LS: She takes L second.Which statement is true?O [F and LS are independent, and PILS|LF) isO LF and LS are independent, and PILS|LF) isO LF and LS are dependent, and PLISILM) is 2.O LF and LS are dependent, and P(LS|LF) is

Answer 1

For this case we can calculate the probablity of LF on this way:

P(LF)= 2/4 = 1/2

And then since she put again the tile the probability of LS we got:

P(LS)= 2/4 = 1/2

And then we can conclude that the best answer would be:.

LF and LS are independent and P(LS/LF)= 1/2 * 1/2 = 1/4
