Question

what is the probability of getting heads when flipping a coin and getting a number greater than or equal to 4 when rolling a single die

Answer 1

possibly 4/6th or 2/3rds would be your answers

Answer 2

The probability of getting hears when flipping a coin is 1 in 2 or 50%.
The probability of getting a number greater than or equal to 4 when rolling a single 6-sided die is 2 in 6 or 1 in 3 or 33.33%

Then you multiply the two together to get a probability of 1 in 6 in 16.66%
