Four students are selected at random from a chemistry class and classified as male or female. list the elements of the sample space s1, using the letter m for male and f for female. define a second sample space s2 where the elements represent the number of females selected.

Solution: The sample space corresponding to four students selected at random from a chemistry class and classified as male or female is:

S1 = {(),(FFFM),(FFMF),(FFMM),(FMFF),(FMFM), (FMMF),(FMMM),(MFFF),(MFFM),(MFMF), (MFMM),(MMFF),(MMFM),(MMMF),()}

Now the second sample corresponding to the number of females selected is:

S2 = {0,1,2,3,4}

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
