(a) Trusts social networking websites a moderate (M) amount (b) Trusts social networking websites completely (C) (c) Trusts social networking websites a lot (A) or completely (C) (d) Does not trust social networking websites at all (N) or only a little (L) ng a 125 (a) The probability that a randomly selected person trusts social networking websites a Round to three decimal places as needed.) nter your answer in the answer box and then click Check Answer parts remaining

Explanation / Answer

N = 177 L = 155 M = 139 A=51 C=27 U=7

N+L+M+A+C+U = 177 +155 +139 +51+27+7 =556

A) Probabality = P(M) = 139 /556 =0.250

B) P(C) = 27/556 = 0.049

C) P(A) + P(C) =

P(C) = 0.049

P(A) = 51/556 = 0.092

P(A) + P(C) =  0.092 + 0.049 =0.141

D) P(N) + P(L) = (177 +156 )/556 = 0.599
