Answer:
The require expected value of x is 
Step-by-step explanation:
Consider the provided information.
Mike will play a game in which he will toss a penny, a nickel, and a dime at the same time.
The probability of head is 
He will be awarded 3 points for each coin that lands with heads faceup.
Let the random variable x represent the total number of points awarded on any toss of the coins.
Thus the expected value is:



Hence, the require expected value of x is 
E = mc2. An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.
The formula for volume of a rectangle prism is length x width x height
volume = 4 x 3 x 65 = 780 cubic meters
