Final answer:
The probability of both independent events E and F occurring is 0.27, calculated by multiplying their individual probabilities.
Step-by-step explanation:
If events E and F are independent, the probability of both E and F occurring (notated as P(E and F)) is the product of their individual probabilities. This is a fundamental property of independent events.
To find P(E and F), just multiply P(E) by P(F):
P(E and F) = P(E) × P(F) = 0.3 × 0.9 = 0.27
Therefore, the probability of both events E and F occurring is 0.27.
