Question

You take a quiz with 6 multiple choice questions. After you​ studied, you estimated that you would have about an​ 80% chance of getting any individual question right. What are your chances of getting them all​ right? The random numbers below represent a simulation with 20 trials. Let​ 0-7 represent a correct answer and let​ 8-9 represent an incorrect answer.

Answer 1

Answer:

Probability of getting all correct is $P_{sucess}=0.262$

Step-by-step explanation:

Since the given events are independent events we have

$P_{sucess}=0.8$

Thus the probability of getting all correct is

$P_{sucess}=P(1)\times P(2)\times P(3)\times P(4)\times P(5)\times P(6)\\\\P_{sucess}=0.8\times0.8\times0.8\times0.8\times 0.8\times 0.8$

$P_{sucess}=0.262$
