Question

a pop quiz has 2 true/false questions. paris used a 10 - trial coin flip to simulate the results of guessing on the quiz. if t represents answering a question correctly, what is the experimental probability of correctly answering both questions by guessing? frequency of observed desired outcome: number of trials: experimental probability: 1/10 3/10 1/2 7/10

Explanation:

Step1: Identify desired outcome

The desired outcome is answering both questions correctly, which is represented by 'TT'.

Step2: Count frequency of desired outcome

Count the number of 'TT' in the trials. There are 3 'TT's. So the frequency of observed desired outcome is 3.

Step3: Determine number of trials

The number of trials is given as 10.

Step4: Calculate experimental probability

The formula for experimental probability $P$ is $P=\frac{\text{Frequency of desired outcome}}{\text{Number of trials}}$. So $P = \frac{3}{10}$.

Answer:

Frequency of observed desired outcome: 3
Number of trials: 10
Experimental probability: $\frac{3}{10}$
