I don’t know how you define “1 block.” Jane’s amount factors into 15 * 5, therefore Peter would factor to 15 * 2 = 30. Is that what you mean by “1 block”?

Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown. 81 * 38 = 3078, which is the product. For 81, 3 * 3 * 3 * 3 are factors. However, 81 and 38 are also factors of 3078.

From your data, with four tosses, you would get 3 tails and one head by chance. The probability of one head would then be 1/4. If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
