The probability of events - 5-card hands. a about a 5-card hand is dealt from a perfectly shuffled deck of playing cards. what is the probability of each of the following events? the hand has at least one club. the hand has at least two cards with the same rank. the hand has exactly one club or exactly one spade. the hand has at least one club or at least one spade. feedback?

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern

so what is the problem what are they asking you to solve

the answer is 8/21

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
