    You multiply the percentages together. What's the chance of getting a head on a coin flip?

    So they all have a 50% chance of being heads. Now multiply the percentages together. It might be easier to write it as \(\large \frac{1}{2}\) when you multiply them.

    the probability of ONE coin being heads is 50% however, we have FOUR coins here, so we must multiply 50% 4 times (0.5)*(0.5)*(0.5)*(0.5) does that make a little more sense?

    um, not quite... put in (0.5)*(0.5)*(0.5)*(0.5) into your calculator and tell me what you get

    \[\large \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2}\]

    right, so convert that decimal to a percent by multiplying by 100
