0.18
To find the probability of heavy snowfall AND schools open, you need to multiply the individual probabilities:
P(H and O) = P(H) * P(O)
P(H and O) = 0.3 * 0.6
P(H and O) = 0.18
Therefore, the probability of heavy snowfall AND schools open is 0.18.
The tree diagram relates snowfall and school closings. Find the following probability. Let H, L, O, and C represent heavy snowfall, light snowfall, schools open, and schools closed, respectively.
