Answer:
0.82 = 82% probability that at least one party will not order drinks
Step-by-step explanation:
For each party, there are only two possible outcomes. Either they will order drinks with their meal, or they will not. The probability of a party ordering drinks with their meal is independent of other parties. So the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
When Ryan is serving at a restaurant, there is a 0.75 probability that each party will order drinks with their meal.
This means that
During one hour, Ryan served 6 parties. Assuming that each party is equally likely to order drinks, what is the probability that at least one party will not order drinks?
6 parties, so n = 6.
Either all parties will order drinks, or at least one will not. The sum of the probabilities of these events is decimal 1. So
We want P(X < 6). So
In which
0.82 = 82% probability that at least one party will not order drinks
Answer:
of the distance
Step-by-step explanation:
We know that a ferry traveled of the distance between two ports in
hours.
In order to calculate what fraction of the distance between the two ports can the ferry travel in one hour we can do the following reasoning :
The rate of the ferry is the same at any time.
The ferry will travel of the distance in
hours.
If we divide each fraction by 3 ⇒
and
We do this to obtain a ''1'' in the numerator of the second fraction (the hours fraction). Now, we can say that :
The ferry will travel of the distance in
hours.
Finally, we multiply each fraction by 7 (in order to obtain the distance for 1 hour) ⇒
and
We found out that the ferry will travel of the distance in 1 hour.
Answer:
D) 0.05, 0.0516, 16%, , 5.16
Step-by-step explanation:
Convert the factions and percentages to decimals to solve the problem quickly. Then, put them least to greatest.
Example: is 0.3125 and 16% is 0.16.
