Answer:
0.40 or 40%
Step-by-step explanation:
Assuming that no student can hold a position at two companies simultaneously, the probability of a student interning at Hawaiian Airlines or Big Island Candies is simply determined by the sum of each individual probability:
[tex]P(H\ or\ B) = P(H)+P(B)\\P(H\ or\ B) = 0.30+0.10 = 0.40 =40\%[/tex]
There is a 40% chance that a student interns at Hawaiian Airlines or Big Island Candies.
