The probability would be 1/6 if the number cube is six-sided and the coin is normal.
First, we will find the probability of the landing on heads with the coin.This would be 1/2 because you have two sides that it could land on and one side you want it to land on.
Next, we will find the probability of getting a five or six with a number cube. This would be 2/6 or 1/3 because there are 6 sides it could land on and two with one of the numbers you want.
Finally, you multiply the two probabilities. 1/3 times 1/2 equals 1/6.
Hope this helps! Have a great day!
