Answer:
P (X≤1) = 0.000
Step-by-step explanation:
Data given:
p = 79% = 0.79
q = 1 - 0.79 = 0.21
n = 16
P (no more than 1 in 16 adults) = P (X≤1)
P (X≤1) = P (X=0) + P (X=1)
We can find the probability by using binomial functions:
![P=\frac{n!}{x!(n-x)!}p^x(1-p)^{n-x}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7Dp%5Ex%281-p%29%5E%7Bn-x%7D)
<h3>P(X=0):</h3>
P(X=0) = (16! / 0!(16-0)!) · 0.79⁰ · 0.21¹⁶
Use calculator to solve:
P(X=0) = 0.000000000798
<h3 /><h3>P(X=1):</h3>
P(X=1) = (16! / 1!(16-1)!) · 0.79¹ · 0.21¹⁵
Use calculator to solve:
P(X=1) = 0.000000034506
<h3>P(X≤1)</h3>
P (X≤1) = P (X=0) + P (X=1)
P (X≤1) = 0.000000000798 + 0.000000034506
P (X≤1) = 0.00000003530
P (X≤1) = 0.000
As 1 is a very low number, its probability is very small
