Daniel picks two cards from a standard deck of 52.

If Daniel draws a club first and does not put it back in the deck, the probability of Daniel picking a club the second time is __________.

1/2

4/17

1/4

1/17

Answer 1

22) A probability distribution of the average time it takes employees to drive to work.

number of minutes employees spend at lunch is discrete the number of minutes can only take integers.

similarly the rest others also.

23) property of binomial distributions:-

the sum of the probabilities of successes and failures is always 1.

24)

There will be 13 clubs in the deck of cards, First card drawn is club and it is not replaced.

now the total card = 51

number of clubs = 12

probability of getting club = 12/51 = 4/17
