Answer: 5 (x > 12) or 5 + m(12 - x) (x < 12)
Step-by-step explanation:
flat fee $5 for first x days +
m dolars per day after x days
So, if x > 12, for 12 days the fee is $5 because it is a flat fee that do not depend of the numbers of day.
But, we do not know how many days x is, so
if x < 12, a person will pay, for 12 days, the m times the difference of the days passed x:
5 + m(12-x)
The experimental probability is the number of specific outcomes divided by the sample size...
P(6)=27/100 (27%)
P(H)=41/100 (41%)
Not sure, but if you meant rolling a 6 AND getting a head then:
P(6 AND H)=(27/100)(41/100)=1107/10000 (11.07%)
