Explanation / Answer

Approximately 12% of people are left-handed. If two people are selected at random, what is the probability of the following events?

Given :-

Left handed probability = 12% = 0.12

Right handed probability = 1- 0.12 = 0.88

A. P(Both are right-handed) = (0.88)^2 = 0.7744
-----------------
B. P(Both are left-handed) = (0.12)^2 = 0.0144
-----------------
C. P(One is right-handed and the other is left-handed)

= 2*(0.12)*(0.88) = 0.2112
-----------------------
D. P(At least one is right-handed)

= 1-[P(bothleft)] = 1-(0.12)^2 = 0.9856
