Question

Eikeen has a bottle cap that is bent. When she tosses the bottle cap it can land either facing up (U) or faxing down (D). The table below shows the results for the last 20 tosses that Eileen has madeBased on the last 20 tosses, what is the estimated probability that Eileen's next toss will land facing up (U)

Answer 1

Answer:

80%

Explanation:

The estimated probability is

number of U's / total number of tosses

Now from the data set, we count that out of 20 tosses, 16 times U was landed; therefore, the probability of getting a U is

$\frac{16}{20}\times100\%=80\%$

Therefore we reason that on our next [21st ] toss, the probability of getting a U is 80%.
