Best of Luck!
The expected value of x is 10.
It is given that the number of dice that are showing an even number is a binomial random variable with n = 4, and p = 1/2 (because half the faces on the die are even and half are odd).
The expected value of this random variable is n*p = 4*1/2 = 2.
The number of points is simply 5 times this random variable, and by the rules of expected value, E(C*Y) = C*E(Y), where C is a constant and Y is a random variable.
Thus E(X) = 5*2 = 10.

Answer:80
Step-by-step explanation:
31.205= 31
4.97=5
1.925=2
31*5/2=155/2=77.5=80 (1 significant figure)
The answer 19 because, 19+8=27, then 27 divided by 9 is equal to 3. If you need to know how I got 19 just let me know!
