Ellen's house is farther from Haley's because 1.41 miles = 7444.8 feet. It is also 898 feet farther away because 7444.8-6547 = 897.8, then you round to the nearest foot, giving you 898 feet.

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.
The probability of success is .06.
This means that
What is the probability of two successes in seven trials?
This is P(X = 2) when n = 7. So
The correct answer is given by option a.
Answer:
There is a 14.71% probability of teacher picking all 3 girls.
Step-by-step explanation:
Initially, there are 18 students, of which 10 are girls. So there is a 10/18 = 5/9 probability that the first student chosen is a girl.
Now, since the first student chosen was a girl, there are 17 students, of which 9 are girls. So there is a 9/17 of the second student chosen being a girl.
Both students picked were girls. Now there are 16 students, of which 8 are girls. So there is a 8/16 = 1/2 probability of the third student chosen in this situation being a girl.
Probability of teacher picking all 3 girls?
We multiply these probabilities:
There is a 14.71% probability of teacher picking all 3 girls.
7/10 + 4/5
- Make 4/5 have a common denominator with 7/10 by multiplying 4/5 by 2/2.
Add 7/10 and 8/10.
Simplify 15/10 by dividing both sides by 5/5.
- 15/10 ÷ 5/5 = <u>3/2 </u>or<u> 1 1/2</u>
