Having trouble with how to solve questions like this:

Eduardwww [97]

In this question there is a small trick that needs to be understood. Basically the ratio in the question is given as a decimal. It can be expressed as a ratio as well.
Ratio of students that voted for winner to the total number of voters = 95:100
The total number of students that voted = 60
Let us assume the common ratio to be = x
then
100x = 60
x = 60/100
= 0.6
Then
The number of votes that the winner got = 95 * 0.6
= 57
So 57 students voted for the winning candidate.

At noodle & company restaurant, the probability that a customer will order a nonalcoholic beverage is .46. Find the probabil

skelet666 [1.2K]

Answer:

0.0021

Step-by-step explanation:

Given:

Probability of ordering a nonalcoholic beverage is, $P(N)=0.46$

Number of samples are $n=10$

Now, the complement of event 'N' is not ordering a nonalcoholic beverage.

Therefore, $P(\overline N)=1-P(N)=1-0.46=0.54$

Now, for a sample of '10' customers, the probability of not ordering a non alcoholic beverage is product of their individual probabilities as all these events are independent events.

Therefore, probability that none of the 10 will order a nonalcoholic beverage is given as:

$=[P(\overline N)]^{10}\\\\=(0.54)^{10}\\\\=0.0021$
