Explanation / Answer

10) option e,c, d and h, probability can take values between 0 and 1(0% and 100%) only

11) a) empirical b) classical c) empirical d) classical e) empirical f) empirical g) subjective

12) a) outcomes{1,2,3,4,5,6}, P(X=2) = 1/6

b) No number above 6, p =0

c) 1,3 and 5 are odd, P(odd) = 3/6 = 1/2

d) 1,3 and 5 are odd plus 4, P(4 or odd) = 4/6 = 2/3

e) a number less than 7 includes all 6 outcomes, P=1

f) {3,4,5,6}, P(3,4,5,6) = 4/6 = 2/3

g) Greater than 2 and even numbers are {4,6}, P(4,6) = 2/6 = 1/3

13) a) There are 36 outcomes in the sum of 2 dice experiment. A sum of 3 will show up if dice shows up as {1,2} or {2,1}, P(sum = 3) = 2/36 = 1/18

b) sum of 7 = {3,4} {4,3}, {5,2} {2,5} {6,1} {1,6}

sum of 11 = {6,5} {5,6}

P(sum = 7 or 11) = 8/36 = 2/9

c) doubles are {1,1}, {2,2} {3,3} {4,4} {5,5} {6,6}

P(doubles) = 6/36 = 1/6

d) sum(less than 9) = 1 - P(9) - P(10) - P(11) - P(12)

X = 9 -> {5,4} {4,5} {6,3} {3,6} = 4/36

X = 10 -> {5,5} {6,4} {4,6} = 3/36

X = 11 -> {6,5} {5,6} = 2/36

X = 12 -> {6,6} = 1/36

sum(less than 9) = 1- 4/36 - 3/36 - 2/36 - 1/36 = 13/18

e) sum greater than or equal to 10

X = 10 -> {5,5} {6,4} {4,6} = 3/36

X = 11 -> {6,5} {5,6} = 2/36

X = 12 -> {6,6} = 1/36

P(sum greater than or equal to 10) = 3/36 + 2/36 + 1/36 = 6/36 = 1/6
