Question

A coin is weighted A coin is weighted so that there is a 59.3%

chance of it landing on heads when flipped. The coin is flipped 13
times. Find the expected number of flips that will result in
"heads".

Answer 1

The expected number of flips resulting in heads, when flipping a weighted coin with a 59.3% chance of landing on heads, over 13 flips is approximately 7.709, which can be rounded to 8 flips.

Step-by-step explanation:

To find the expected number of flips that will result in "heads" when a coin weighted with a 59.3% chance of landing on heads is flipped 13 times, you can use the concept of expected value in probability. The expected value is calculated by multiplying the probability of an event by the number of trials. In this case, the expected number of heads can be calculated by multiplying the probability of getting a head on a single flip (0.593) by the number of flips (13).

Expected number of heads = Probability of heads × Number of flips


Expected number of heads = 0.593 × 13


Expected number of heads = 7.709

Therefore, the expected number of flips resulting in heads is approximately 7.709, which can be rounded to 8 if we are considering whole number of flips.
