Find the probability of each event. Answer IN FRACTION form.

A mechanic working under a car requires four different size wrenches from his
toolbox, which contains eleven different wrenches. Reaching for his toolbox, he grabs four of them at random. What is the probability that the mechanic has all of the wrenches he needs?

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.
