Answer:
P(odd)- 1/2
P(even)-1/2
p(odd and then even=1/2*1/2)
= 1/4 or 25%
Of the 27 players trying out for the school basketball team, 8 are more than 6 feet tall and 7 have good aim. What is the probability that the coach would randomly pick a player over 6 feet tall or a player with a good aim? Assume that no players over 6 feet tall have good aim. A. 7/15 B. 6/15 C. 7/9 D. 5/9
The Answer Is
--------5/9--------
Answer:
5.96% probability that exactly 3 people in the sample are afraid of being alone at night.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they are afraid of being alone at night, or they are not. The probability of a person being afraid of being alone at night is independent of any other person. So we use the binomial probability distribution 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.
5% of Americans are afraid of being alone in a house at night.
This means that 
If a random sample of 20 Americans is selected, what is the probability that exactly 3 people in the sample are afraid of being alone at night.
This is P(X = 3) when n = 20. So


5.96% probability that exactly 3 people in the sample are afraid of being alone at night.
So, we will start by subtracting the orange cats
5-2=3 orange cats left
Then the black cats
14-6=8
Now we will add them back together:
8+3=11 Cats remaining
Answer:
<u>There are 60 toddlers in the preschool class</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Percentage of the toddlers in a preschool class drink water with their lunch = 5
Number of the toddlers in a preschool class drink water with their lunch = 3
2. How many toddlers are in the class?
We'll solve the question, using the Direct Rule of Three, this way:
Percentage Toddlers
5 3
100 x
*******************************
5x = 3 *100
5x = 300
x = 300/5
x = 60
<u>There are 60 toddlers in the preschool class</u>
