I am stuck on this question.

Suppose you have an experiment where you flip a coin three times. You then count the number of heads. a} State the random variable. Irv X = the number of heads ipped when you ip a coin three times v I" b) Write the probability distribution for the number of heads. Make sure to put the values of X from smallest to largest. x P01} 0., g. 1., ' g; 2., ' g; 3., g. c) If you were to draw a histogram for the number of heads, what shape would it be? Bellshaped v V d) Find the mean number of heads. Round final answer to 3 decimal places. Write your units in the second box. Which of the following is the correct symbol for the mean of a probability distribution? Which of the following is the correct interpretation of the mean? If you ip a coin 3 limes over and over, you can expect to get an average of 1.5 heads for every 3 ips v V e} Find the standard deviation for the number of heads
