Draw a pie chart looking wheel with 30% and 70% and spin the wheel three times and see what it lands on each time

Answer: I understand that you want to know the probability of raining in the next 3 days (so rains every day).

For this, you have 1/3 probability for each day, so if this happens 3 times, the probability will be the product (1/3)*(1/3)*(1/3)= 1/27.

so you have a 3.7% chance of seeing rain the three days.

A way of simulating all the probabilities, is with two D10 (dices with 10 faces)

here if you throw bout dices and get a 0,1,2 or 3 (rounding up) will rain the three days, if you get ani other number, there will be at least one day with no rain.
