I am stuck on probability questions again my teacher never explains any of these things and we are stuck learning it from the book so can anyone please help me.
1. Suppose the two joker cards are left in a standard deck of cards. One of the jokers is red and the other is black. A single card is drawn is from the deck of 54 cards,but not returned, and then a second card is drawn. Determine the probability of drawing the red joker or a red ace on either draw.
I know it something like 1- (Probability of not getting an ace or a club) but how do we find that number because the card is not returned. The probability of a joker is 1/54 and the aces is 2/53 if its seconds. So how would I do this.
Now i need help with this question.
2. A paper bag contains a mixture of 3 types of candy. There are ten 10 chocolate bars, seven fruit bars, and three packages of toffee. Suppose a game is played in which a candy is randomly taken from the bag, replaced, and then a second candy is drawn from the bag, if it was the same type as the one that was drawn the first time, calculate the probability of each of the following.
a)you will be able to keep the chocolate bar
b)You wont be able to keep any of them.
This one all i know for a is that the P(chocolate)=10/20
For "b" i have no clue how to do it.
Finally the last question i need help with please.
3. A basketball player has a success rate of 80% for shooting free throws.
Calculate the following probabilities.
i) She will make 3 out of 5 attempts
ii)She will miss all 5
iii)She will make the first 3 and miss the next 2.
Sorry for posting all these questions but i really need help with them because it really hard to learn from a book and your help is greatly appreciated. Unless someone can explain a very good way on how to tackle these problems or where i can get help, i will probably need help again.
