3.2.1. an investment analyst has tracked a certain bluechip stock for the past six months and found that on any given day, it either goes up a point or goes down a point. furthermore, it went up on 25% of the days and down on 75%. what is the probability that at the close of trading four days from now, the price of the stock will be the same as it is today? assume that the daily fluctuations are independent events.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
