Question

Determine the theoretical probability of Tossing two heads with two coins Rolling a 2 or 5 with one die

Answer 1

The theoretical probability of tossing a heads with one coin is 1/2 since there are 2 sides. You have to multiply 1/2*1/2, because there are now two coins. 1/2*1/2=1/4 so the probability of rolling 2 heads on 2 coins is 1/4. The probability of rolling a 2 or 5 on a dice is 2/6 or 1/3. This is because there is a total of 6 sides on a dice and 2 or 5 are 2 possibilities so the probability would be 2/6. You can simplify this to 1/3. You now have to multiply 1/4*1/3 since it says 2 heads with 2 coins. 1/4*1/3=1/12. 1/12 is your final answer.
