So we see that the probability of it landing head the first time around is basically one half. So the probability of event number one taking place is one half and likewise the probability of independent event number two taking place, the second coil flip, coin flip is also one half. And because they're independent, to find the actual probability of these two events taking place we have to apply the product rule. We multiply them by one another and we basically get one fourth which is equivalent to zero point 25. And if we multiply by 100 we get 25%. So remember this is zero point 25 out of one or equivalently 25%.
