Two cards are drawn at random, from a standard deck. ( 52 cards, 13 hearts, 13 diamonds, 13 spades, 13 clubs) Are the outcomes of the two cards independent? Select all true statements

If the first card is replaced, the outcomes are independent

Replacing the first card restores the orginal sample space

If the first card is not replaced, the outcomes are not independent, because removing the first card changes the sample space,

If the first card is replaced, the outcomes are dependent

Two cards are drawn at random, from a standard deck. ( 52 cards, 13 hearts, 13 diamonds, 13 spades, 13 clubs) If the first card is replaced before the second one is drawn, what is the probability that both cards will be hearts?

P( heart and heart) = 13/52 * 13/52 = 0.063

P(heart and heart) = 1/52 * 1/52 =0.000369

P(heart and heart) = 1/4 * 1/4 = 1/17=0.0625

There are 5 multiple choice questions on an exam, each with 4 possible answers. Use the multiplication rule of counting to determine the number of possible aswers sequences for the five questions. Only one of the sets can contain all five correct answers. If you are guessing, so that you are as likely to choose one sequence of answers as another, what is the probability of getting all five answers correc?

P( all correct) = 1/16 = 0.0625

P( all correct) = 1/ 1024= 0.00098

P( all correct) = 1/ 2048=0.000488
