At a music store in New York City, 58 people entering the store were selected at random and were asked to choose their favorite type of music. Of the 58, 14 chose rock, 14 chose country, 6 chose classical and 24 chose something other than rock, country, or classical.
a) Determine the empirical probability that the next person entering the store favors rock music
b) Determine the empirical probability that the next person entering the store favors country music,
c) Determine the empirical probability that the next person entering the store favors something other than rock, country, or classical music,

Step-by-step explanation:

all you need is khan academy go to khan academy then click math then search the math your learning an dit should tell you how to do it

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
