You roll a number cube and flip a coin. find the probability of rolling an even number and flipping heads. write your answer as a fraction in simplest form.
Supposing that the number are 1-6 there are 3 even numbers, so the probability to roll an even number is 3/6=1/2. Probability of flipping head is 1/2 so combined probability=1/2×1/2=1/4.
