34% democrats, 25% republicans, 2% liberals and the rest. If 30 random people are selected. You would expect about (blank) democrats, give or take about (blank). DO STEP BY STEP PLZ

for 30 people, the probability of picking a democrat is 34%=(34/100)=0.34

but the selection is randomly done 30 times, therefore, possible number of democrats will be;

=0.34*30

=10.2

round off to the nearest whole number,

=10 democrats
