Suppose that the die is rolled twice, rather than once. find the probability of rolling an even number on at least one die. find p(aon first toss or a on second toss)

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

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.
