What is the probability of getting 10 heads in 20 flips?

WebFeb 12, 2010 · So there are two 50% probabilities that you need to combine to get the probability for getting two heads in two flips. So turn 50% into a decimal --> 0.5 Multiply the two 50% probabilities together --> 0.5 x 0.5 = 0.25. Therefore, 0.25 or 25% is the probability of flipping a coin twice and getting heads both times. WebP(First coin flip = HEADS) = 0.5 = 50%. P(Second coin flip = HEADS) = 0.5 = 50% (not dependent on the previous coin flip) ∴P(Both Coin Flips = HEADS) = (0.5)*(0.5) or (1/2)*(1/2) = (1/4) = (0.25) = 25%. Another approach: If we tabulate the possibilities of the outcomes of the two coin flips we get: nepal public holidays 2018
