Hello, I was playing poker and I was 31% to win the game when we were all-in but I lost. However, this loss was insignificant for I had 3x as many chips than him therefore we became even in chips. Later, when the chips were even, I was 42% to win the game and I won therefore winning me the game. My question is ... what were my total odds of winning this game? Ultimately, my odds of winning this game has to be higher than 42% because I was 42% at one point for the win. However, I did have an additional chance of winning at 31%. What is the formula to figure this out? I would think my odds of winning would be something like 42% + ?%. Let me know please, thanks! Also, let me know what the odds would be if it was 80% and 50% =)

Products like Lysol claim to kill 99 per cent germs, as do most household products. So, what is the 1% ?
What if that 1% is the most powerful kind? Or do they just claim that, and the percentage is actually higher, just so that you can't lay blame on them or sue them.

Archeologists can determine the age of artifacts made of wood or bone by measuring the amount of the radioactive isotope 14^C present in the object. The amount of isotope decreases in a first-order process. If 15.5% of the original amount of 14^C is present in a wooden tool at the time of analysis, what is the age of the tool? The half-life of 14C is 5730 yr. (answer in units of years)

In the javelin throw at a track-and-field event, the javelin is launched at a speed of 28 m/s at an angle of 39° above the horizontal. As the javelin travels upward, its velocity points above the horizontal at an angle that decreases as time passes. How much time is required for the angle to be reduced from 39° at launch to 17°?
