ClimateYou Commentary: Climate Change & What we can do

If you toss a coin, the odds are equal that it will land heads or tails. It’s an even bet, 50-50 heads or tails. Say it lands heads. What are the odds that a second toss lands heads? Still 50-50. Say it lands heads again. A third toss? Still 50-50. But if you ask a different question, What are the odds that two coin tosses both land heads? The odds are 1 in 4 — HH, HT, TH, TT.
