Four speed skaters, marco, naim oliver and pedro, compete in a relay race where they all agree that naim will be the last
skater. then, they try to decide whether or not oliver should be the first skater in the race
which subset, a. of the sample space shows the complement of the event in which oliver is the first skater in the race?
a (mopn, pmon)
a(opmn, ompn)
a = {mopn, mpon, opmn, pomn)
a = {mopn, mpon, pmon pomn)

what is the image?

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.
