18% of a population eats yogurt daily. what is the probability that, in a group of 10 people, 4 of them eat yogurt daily?
0.0032 0.072 0.067 0.00032

The probability that, in a group of 10 people, 4 of them eat yogurt daily is 0.067

Step-by-step explanation:

In this case we can apply a Binomial distribution in which there are n events and every event have a probability p to get a success. Then, the probability of x is:

Where x is the number of people who eat yogurt daily, n is the total number of people and p is the probability of eats yogurt daily.

Additionally nCx is calculated as:

So, for the question we know that:

n=10

p=0.18

x=4

Replacing this values on the equation, we get:

P(4)=0.067

Finally, the probability that, in a group of 10 people, 4 of them eat yogurt daily is 0.067

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
