Step-by-step explanation:
Answer: The probability that none of the calls would result in a reservation would be 0.72%.
Since there is an 18% chance that there would be a reservation, then there is a 72% chance that there is not a reservation.
Our goal is to determine the likelihood that there are no calls. Or that the 72% chance event happens 15 times.
We can use the following expression to find that repeated probability.
(0.72)^15 = 0.0072 or 0.72%
3*3*3*3=81 so your answer is A
Answer:
234 students and 151 family members
Step-by-step explanation:
Let x be the amount of students and y be the amount of family members...
x+y=385
x=y+83
We can solve using substitution...
y+83+y=385
Combine like terms
2y+83=385
Subtract 83 from both sides
2y=302
Divide both sides by 2
y=151
x=151+83
x=234
There were 234 students and 151 family members.
