There are 119 electricians listed in the yellow pages of the phone book. If a customer selects an electrician at random, what is the probability that Andy (an electrician) will be selected? What is the probability as a percent? Round to the nearest tenth of a percent.
The probability of an certain possibility, is the number favoured possibilities divided by the total number of possibilities .
I don't really understand...
say i rolled a dice and was hoping to roll a three or four . the dice has six faces so there are 6 possibilities, i only want a three or four so there are 2 favoured possibilities the probability of being successful is \[2/6 =1/3\approx33.3\%\]
So I would divide 119 by 1?
almost , it's the other way around
