<span>the probability of an event and the probability of its complement add up to 1
because the total events are the even it self and its compliment, so its probability equal to 1 because these are all the possible events that will occur. for example a coin toss, an event head will happen 0.5, and its complement is tails which will also happens 0.5</span>
No
Arithmetic sequence has terms which decrease or increase by the same amount
for example 3,6,8,12 ....
this sequence is geometric where the terms are obtained by multiplying previous term by 10
13 + [128 + (-24 - 5b)/2)]/3 - 45 = 0
(52 - 5b/2)/3 = 32
52/3 - 5b/6 = 32
14.67(6) = -5b
b = 88/-b
b= -17.6
