The probability of a successful landing of an airplane using a flight simulator is given by 0.70. Six student pilots, chosen at random and independently, are invited to try to fly the plane using the simulator. What is the probability that two of the six students successfully land the plane using the simulator? Also calculate the average of students who successfully land the aircraft. Get DP(X). Interpreter
Question
Answer:
Probability that 2 of 6 landed successfully
$$(6C2)(0.7^2)(0.3^4)=0.0595$$
