40 cotton candy cones
simplify:
30/75 (about this, just simplified version)=10/25=40/100
+10 is answer
40 is final answer
Answer as a fraction = 1/25
Answer in decimal form = 0.04
Answer in percent form = 4%
Explanation:
There are 5*5 = 25 different outcomes, of which only one outcome has 5,5. The probability of picking two 5s is 1/25 = 0.04 = 4%
Answer:
you take the numbers from 1 to 9 in descending order and divide them by the numbers from 1 to 9 in ascending order you get a really good approximation of 8 that is accurate up to eight digit. I also found some other approximations, but their less accurate and interesting.
Step-by-step explanation:
The answer is the last one because you are plugging the x values in for x and solving it out for y.
Answer:
a) 0.2182
b) 0.0691
c) 0.9309
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly b successes on n repeated trials, and B can only have two outcomes.
In which is the number of different combinations of b objects from a set of n elements, given by the following formula.
And p is the probability of B happening.
In this problem we have that:
Bin(20,0.2).
This means that
(a) P(B=4).
(b) P(B≤1).
(c) P(B>1).
Either B is less than or equal to 1, or B is larger than 1. The sum of the probabilities of these events is decimal 1. So
We have that, from b),
So
