There are three children in the mccomb family. which sample space represents the gender order, m (male) or f(female), in which the children could have been born? a) {mmm, mmf, mfm, mff}

b) {mmm, mmf, mff, fmm, ffm, fff}

c) {mmm, mmf, mff, fmm, fmf, ffm, fff}

d) {mmm, mmf, mfm, mff, fmm, fmf, ffm, fff}

B){MMM, MMF, MFF, FMM, FFM, FFF}  

Step-by-step explanation:

Given: There are three children in the McComb family.

Since , there are two possibility for each member of a family, i.e. Male(M) and Female (F).

Now, the number of elements in the sample =

As sample contains each and every possible outcomes.

Therefore, the sample space = {MMM, MMF, MFF, FMM, FFM, FFF}

Step-by-step explanation:

d

one of each metals

step-by-step explanation:

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.
