Assume that when adults with smartphones are randomly selected, 54% use them in meetings or classes. if 66 adult smartphone users are randomly selected, find the probability that exactly 44 of them use their smartphones in meetings or classes.i figured out that n=6, x=4, and p=0.54.  i think i am supposed to use the binomial formula but i don't know how to.

N - number of sample = 66

X = 44

P=0.54

q= 1-0.54

66 C 44 * 0.54^44 * (1-0.54)^(66-44)
