if you flip two coins 36 times, what is the best prediction possible for the number of times both coins will land on tails? times
Answer
Explanation:
Step1: Calculate probability of both tails
The probability of a single - coin landing on tails is $\frac{1}{2}$. For two independent coins, the probability of both landing on tails is $\frac{1}{2}\times\frac{1}{2}=\frac{1}{4}$.
Step2: Find expected number of times
The expected number of times an event occurs in $n$ trials is given by $n\times P$, where $n = 36$ (number of trials) and $P=\frac{1}{4}$ (probability of the event). So, $36\times\frac{1}{4}=9$.
