Answer:

0.2700

Step-by-step explanation:

-Notice that this is a binomial distribution with p=0.52, n=4 and x=3.

-The formula for the binomial probabilities is given as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}$

The probability than in 4, exactly 3 order their food on the go is:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X=3)={4\choose3}0.52^3(1-0.52)^1\\\\=0.2700$

Hence, the probability that exactly 3 order their food on the go is 0.2700
