Follow the formula given below.
P(Mar and Vacation) = P(vacation l march) x P(March)
So it was given above that 5% is the probability that it is March and someone's vacation.
0.05 = P(vacation l march) x ( 1/12)
1 0.05
P(vacation l march)= ------- x --------
12 1
P(vacation l march) = 0.6
So the answer is 60% probability that you will have a vacation given that the month is March.
Answer: Each student need to pay $ 17.55 to go on the field trip.
Step-by-step explanation:
As per given, Total students = 25+24 = 49
Program cost per student = $10
Bus cost = $235.20
Charge per student =$2.75
Total cost of trip = (Program cost+ Charge per student ) (Total students)+ Bus cost
Total cost of trip = $ [( 10 +2.75)(49) + 235.20]
= $[12.75(49)+235.20]
= $ [624.75+235.20]
= $ 859.95
Each student have to pay = (Total cost of trip ) ÷ (Total students)
= (859.95 ) ÷ 49
= $ 17.55 [approx.]
Hence, Each student need to pay $17.55 to go on the field trip.
