Answer:

Probability of randomly selecting an insect = 1/3

Step-by-step explanation:

Total number of flashcards, n(Total) = 30

Number of insects, n(Insects) = 10

The probability of selecting an insect, P(insect) = n(Insect)/n(Total)

P(insect) = 10/30

P(insect) = 1/3

Probability of randomly selecting an insect = 1/3
