When you are determning the probability of an event why must the probability be between 0 and 1

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
