Question
what is the estimated probability of a coin if it was heads=20 and tails=5
Solution
The probability of getting heads or tails on a coin flip is calculated by dividing the number of desired outcomes (either heads or tails) by the total number of outcomes.
In this case, the total number of outcomes is the sum of the number of heads and tails, which is 20 (heads) + 5 (tails) = 25.
-
The probability of getting heads is calculated as follows: Number of heads (20) divided by total outcomes (25) = 20/25 = 0.8 or 80%.
-
The probability of getting tails is calculated as follows: Number of tails (5) divided by total outcomes (25) = 5/25 = 0.2 or 20%.
So, the estimated probability of getting heads is 80% and for tails is 20% if the coin was flipped 25 times resulting in 20 heads and 5 tails.
