Answer:
0.2027 is the probability that exactly 3 out of 9 adults use their smartphones in meetings or classes.
Step-by-step explanation:
We are given the following information:
We treat adult using smartphones in meetings or classes as a success.
P(Adult using smartphone) = 46% = 0.46
Then the number of adults follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 9
We have to evaluate:
0.2027 is the probability that exactly 3 out of 9 adults use their smartphones in meetings or classes.
The side length of the new square would be 9. When you dialate you multiply by the square factor, so 1/2 times 18 equals 9.
