Cora is playing a game that involves flipping three coins at once let the random variable H be the number of coins that land showing heads. Here is the probability distribution for H.

Step-by-step explanation:

Given (Missing from the question):

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:
