a variable is a letter and a factor is a multiple

answer:

1) 60% have a valid license, so 40% do not have a valid license

of the 60% with a valid license, 70% had no violations (100%-30%=70%)

70%*60%=0.7*0.6=0.42=42% had   no violations

of the 40% that had no valid license, 80% had no violations (100%-20%=80%)

80%*40%=0.8*0.4=0.32=32% had no violations

42%+32%=74% with no violations

2)what is the probability of drawing an ace or a heart

there are 4 aces and 13 hearts but one heart is an ace so you can't use the ace of hearts twice

p=(4+12)/52=16/52=4/13 or

p=(3+13)/52=16/52=4/13, or

p=(4/52)+(13//52)=(4+13-1)/52=16/52=4/13
