The city carnival is holding a raffle. Every raffle ticket purchased will go into a large bin. At the end of the day, one ticket will be drawn at random for the grand prize. Lewis bought 2 tickets, Raul bought 6 tickets, and Amy bought 8 tickets.

If a total of 350 tickets were sold, what is the probability that either Raul or Amy will win the grand prize?
A. 3/175

B. 1/175

C. 4/175

D. 1/25

D. 1/25

Step-by-step explanation:

8 + 6 = 14 tickets

14/350 = 2/50

2/50 = 1/25

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
