Since there are six sides to the dice, the probability of rolling a number less than 5 is 4/6
There are only two sides to a coin. Therefore, the probability of flipping tails is 1/2
To find what the probability of getting both things, you simply multiply both fractions.
1/2 X 4/6
1 X 4 = 4
2 X 6 = 12
4/12
Since the answer should be given in it's "simplest form", you should cancel it down. Since 12 is also divisible by 4, you divide both sides by 4.
4 ÷ 4 = 1
12 ÷ 4 = 3
1/3
The probability of rolling a number less than 5 and flipping tails is 1/3
