Answer:

[tex]P(H <3) = 0.875[/tex]

Step-by-step explanation:

Given (Missing from the question):

[tex]\begin{array}{cc}{H}&{P(H)&0&0.125&1&0.375&2&0.375&3&0.125\end{array}[/tex]

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:

[tex]P(H <3) = P(H = 0) + P(H = 1) + P(H = 2)[/tex]

[tex]P(H <3) = 0.125 + 0.375 +0.375[/tex]

[tex]P(H <3) = 0.875[/tex]

Answer:

0.5
