Answer:
![P(x = 3) = 0.1700](https://tex.z-dn.net/?f=P%28x%20%3D%203%29%20%3D%200.1700)
Explanation:
Given
![n = 15](https://tex.z-dn.net/?f=n%20%3D%2015)
![p = 0.3](https://tex.z-dn.net/?f=p%20%3D%200.3)
Required
Determine P(x = 3)
This is calculated using:
![P(x) = ^nC_xp^x(1-p)^{n-x}](https://tex.z-dn.net/?f=P%28x%29%20%3D%20%5EnC_xp%5Ex%281-p%29%5E%7Bn-x%7D)
So, we have:
![P(x = 3) = ^{15}C_3*0.3^3*(1-0.3)^{15-3}](https://tex.z-dn.net/?f=P%28x%20%3D%203%29%20%3D%20%5E%7B15%7DC_3%2A0.3%5E3%2A%281-0.3%29%5E%7B15-3%7D)
![P(x = 3) = ^{15}C_3*0.3^3*(1-0.3)^{12}](https://tex.z-dn.net/?f=P%28x%20%3D%203%29%20%3D%20%5E%7B15%7DC_3%2A0.3%5E3%2A%281-0.3%29%5E%7B12%7D)
![P(x = 3) = 455 *0.027*(0.7)^{12}](https://tex.z-dn.net/?f=P%28x%20%3D%203%29%20%3D%20455%20%2A0.027%2A%280.7%29%5E%7B12%7D)
![P(x = 3) = 455 *0.027*0.0138412872](https://tex.z-dn.net/?f=P%28x%20%3D%203%29%20%3D%20455%20%2A0.027%2A0.0138412872)
![P(x = 3) = 0.17004021325](https://tex.z-dn.net/?f=P%28x%20%3D%203%29%20%3D%200.17004021325)
![P(x = 3) = 0.1700](https://tex.z-dn.net/?f=P%28x%20%3D%203%29%20%3D%200.1700)
