Mandy and 5 of her friends are playing a board game. One of the friends argues that the game is not fair because they have played 7 times and he has yet to win. If the game is actually fair, what is the probability of not winning 7 games in a row? If necessary, round your answer to the nearest tenth of a percent.

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

angle efh= angle egh

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
