50% times 7 equals 50%.
Same with the forecast. 50% chance of rain for each day means that the chance for rain that week is 50%. If it rains one day then the chance of rain that day is 100% but the chance of it raining again for the balance of the days is still 50% each day and 50% for the rest of the days.
Think of it this way. If you went into a store and bought ten items each selling at 10% off, you wouldn't be getting 100% off because you bought ten items.
