The varsity soccer team has 20 players. Three of the players are trained to be goalies and the remaining 17 players can play any position. Only 11 players may be on the field at the same time. a) We want to find the number of possible groups of 11 players the coach can choose. Is this a permutation or combination? WHY? b) If the coach wanted to choose 11 starters at random by drawing names from a hat, how many possible groups of 11 starters could the coach choose? c) The coach want to make sure there is exactly one goalie on the field. How many ways can the coach choose a lineup of 11 players if exactly 1-player must be a goalie?

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

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
