Probability is the link between Descriptive Statistics and Inferential Statistics. So get out your dice, coins, and cards. To get started, what is the probability of getting either a king or a red card if I pick a card at random from a standard deck of cards?

Also, let's say that a pro basketball player is a career 80% free throw shooter. Suppose the player attempts 4 free throws in a game. What is the probability that the player will make 2 of these 4 shots? As a first cut, do you think that the probability will be high or low?

Expert Solution

total number of cards in a deck=52

total numebr of king =4 and total red cards =26

as there are 2 card which are king as well red therefore number of cards which are king or red =4+26-2=28

hence probability of getting either a king or a red card =28/52=7/13

2) as expected number of success =np=4*0.8 =3.2 whcih is higher than 2 therefore probability of happenign that should be low.

probability that the player will make 2 of these 4 shots = =0.1536
