You are going to play mini golf. A ball machine that contains 2121 green golf balls, 2424 red golf balls, 2121 blue golf balls, and 1919 yellow golf balls, randomly gives you your ball. What is the probability that you end up with a blue golf ball? Express your answer as a simplified fraction or a decimal rounded to four decimal places.

0.2471

Step-by-step explanation:

The total number of balls in the ball machine is ;

2121+2424+2121+1919= 8585

Therefore the probability of picking a blue golf ball as;

2121/8585= 0.247059

= 0.2471 to 4 decimal places.

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.
