Answer:
![P(H](https://tex.z-dn.net/?f=P%28H%20%3C3%29%20%3D%200.875)
Step-by-step explanation:
Given (Missing from the question):
![\begin{array}{cc}{H}&{P(H)&0&0.125&1&0.375&2&0.375&3&0.125\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D%7BH%7D%26%7BP%28H%29%260%260.125%261%260.375%262%260.375%263%260.125%5Cend%7Barray%7D)
And the required question is:
Determine the P(H < 3)
P(H <3) implies that: P(H = 0) or P(H = 1) or P(H = 2)
So, we have:
![P(H](https://tex.z-dn.net/?f=P%28H%20%3C3%29%20%3D%20P%28H%20%3D%200%29%20%2B%20P%28H%20%3D%201%29%20%2B%20P%28H%20%3D%202%29)
![P(H](https://tex.z-dn.net/?f=P%28H%20%3C3%29%20%3D%200.125%20%2B%200.375%20%2B0.375)
![P(H](https://tex.z-dn.net/?f=P%28H%20%3C3%29%20%3D%200.875)
