Answer:
0.375, 0.125, 0.5
Step-by-step explanation:
given that you are taking a T/F exam and you have no idea at all about the answers to the last three questions.
Probability for correct guess = 0.5 remains constant for each of the three questions
X - no of questions is binomial with n =3 and p = 0.5
1) the probability that you guessed right on exactly one of the three questions
= P(X=1)
= 
2) the probability that you guessed right on zero of the three questions
= 
3) the probability that you guessed right on at least two of the questions
=
Let the number be 'x'.
Three times a number will then give 3x
Therefore the equation will be:
Assuming the probability of selecting one man is 1/2 and independent events,
