the Assume that when adults with smartphones are randomly selected, 46% use them in meetings or classes. If 8 adult smartphone users are randomly selected, find the
probability that exactly 6 of them use their smartphones in meetings or classes.
In this problem we have a Binomial Probability Distribution
n=8
k=6
p=46%=0.46
q=1-p=0.54
[tex]P(x=k)=\frac{n!}{k!(n-k)!}\cdot p^k\cdot q^{(n-k)}[/tex]substitute the given numbers
[tex]P(x=6)=\frac{8!}{6!(8-6)!}\cdot0.46^6\cdot0.54^{(2)}[/tex]
