Answer:

The probability that Shasta will eat longhorn or collie is 80%

Step-by-step explanation:

The probability of Shasta to eat longhorn is 50%.

And the probability of Shasta to eat collie is 30%

Therefore, you need to add up those two percentages to get the probability of eating longhorn or collie.

50%+30% = 80% or 0.8
