The probability of getting exactly two heads
WebbWith combinatorics, we take 3 flips and choose 2 heads, which is 3!/[(2!)(3-2)!] = 3*2*1/[(2*1)(1)] = 3. Note that this is the same number as taking 3 flips and choosing 1 …

WebbGetting two heads out of 4 can be portrayed is, disregarding order: HHTT (H=heads and T=tails) Multiplying their probabilities will yield ( 0.5) 4, but as for ordering, we get 4! / ( 2! ⋅ 2!) due to repetition, which is the same as 4 C 2. So our answer is ( 4 2) ⋅ ( 0.5) 4 which is … Webb8 juli 2024 · We have to calculate P ( T ∩ T). Using the law of total probability, we can calculate the probabliy of getting a head, P ( H) = P ( H ∩ C 1) + P ( H ∩ C 2) = P ( H C 1) P ( C 1) + P ( H C 2) P ( C 2) = .5 ∗ .5 + .9 ∗ .5 = .25 + .45 = .7 Similarlity we can calculate the probability of gettting a tail,
