Question
A fair die and coin are tossed once. What is the probability of a head on the coin and an even number of die showing up?

Answer
Hi again, Hassan,

This is actually two probability problems, one for the coin and one for the die. When you have the two probabilities, you multiply them.

The probability for the coin getting heads is 1/2, and the probability for the die to be even is also 1/2 (have of the numbers are odd and have are even). So, the probability of both occuring is 1/2 * 1/2 or 1/4.

I hope this helps,
Jack

Expertise

I can answer most questions in Math up to single-variable Calculus, including infinite series. I like to think very much, so questions with a lot of twists and turns are highly welcomed! Mathematical questions related to computer science are also highly welcomed! I can also answer some basic questions in discrete mathematics (logics, sets, some algorithms, basic number theory). I am also studying physics (mechanics in particluar), so I am willing to answer some questions relating to it.

Experience

Majoring in Mathematics.

Education/Credentials
I am sophomore/junior status in college working towards bachelor's degrees in Computer Science and Mathematics.
