Now add them all up: since there were 10 different orders, that is 0.02048 times 10= 0.2048. She could get SFSSF which has probability 0.02048.
She could get FSSSF which has probability 0.02048. She could get FSSFS which has probability 0.02048. She could get FFSSS which has probability 0.02048. She could get FSFSS which has probability 0.02048. She could get SFSFS which has probability 0.02048- you should have seen by now that just changing the order of the numbers doesn't change the product. (Writing "S" for success and "F" for failure.) Well, if you reall don't know how to do permutations, you could try this:(it's really doing the permutations "by hand".) So please can anyone explain step by step on how to do these questions or give me a link to a site please. I also have no idea how to do this questions either.
Determine whether a two-engine plane is safer that a four engine plane if the chance that an engine fails is 1 in 2. Suppose that engine failures are independant events. This one i have no idea how to do because we are still on condition probability so i don't kno how to do permutations or anythingĪn airplane can make a safe landing if at least half of its engines are working. Iii)She will make the first 3 and miss the next 2. A basketball player has a success rate of 80% for shooting free throws. This is the answer my teacher told me but i have no idea how to get 51/54 or the 50/53 so can anyone please explain this to me.Ģ. Determine the probability of drawing the red joker or a red ace on either draw. A single card is drawn is from the deck of 54 cards,but not returned, and then a second card is drawn. One of the jokers is red and the other is black.
Suppose the two joker cards are left in a standard deck of cards. I have lots of question on probability because my teacher makes us learn from the book so i need help.ġ.
