sam has worn a green shirt on 10 of the last 20 days. considering this data, how many times would you expect sam to wear a green shirt in the next 12 days? times
Answer
Explanation:
Step1: Calculate the probability
The probability $P$ of Sam wearing a green - shirt is the number of days Sam wore a green shirt divided by the total number of days. $P=\frac{10}{20}=\frac{1}{2}$.
Step2: Predict the number of times
To find the expected number of times Sam will wear a green shirt in the next 12 days, we multiply the probability by the number of days. Let $n$ be the expected number of times. $n = P\times12$. Substitute $P=\frac{1}{2}$ into the formula: $n=\frac{1}{2}\times12 = 6$.
