Doesn't the probability of tossing 4 coins equals 24 which is 64 outcomes?
No. The number of outcomes is 24 which is 16, not 64. Furthermore, probability is a number that is associated with an outcome and is a number in the range [0, 1]. Neither 16 nor 64 are number in the relevant range.
What is the probability of getting 6 heads in tossing 6 coins in 6 tosses?
The probability of tossing 6 heads in 6 dice is 1 in 26, or 1 in 64, or 0.015625. THe probability of doing that at least once in six trials, then, is 6 in 26, or 6 in 64, or 3 in 32, or 0.09375.
What is the probability of winning two games with the same probability of 0.8?
The probability of winning two games with the same probability of 0.8 can be calculated by multiplying the probability of winning the first game (0.8) by the probability of winning the second game (0.8). Therefore, the probability is 0.8 * 0.8 = 0.64, or 64%.
