Answer:
The expectation the instructor to send each day
E(X) = 3.65
Step-by-step explanation:
Given data x : 0 1 2 3 4 5
P(X=x) : 0.05 0.05 0.1 0.1 0.4 0.3
The given data satisfy the two conditions
I) Given all probabilities are p₁(x) ≥0
ii) sum of all probabilities is equal to one
0.05 + 0.05 + 0.1 + 0.1 + 0.4 +0.3 =1
Therefore given data is discrete probability distribution
<u>Expectation</u> :-
suppose a random variable X assumes the values
with respective probabilities
, then the Expectation or Expected value of X , denoted by E(X) = ∑pi xi
![E(X) = 0X0.05+1X 0.05 +2X 0.1 +3X 0.1 +4X0.4 +5X 0.3](https://tex.z-dn.net/?f=E%28X%29%20%3D%200X0.05%2B1X%200.05%20%2B2X%200.1%20%20%2B3X%200.1%20%2B4X0.4%20%2B5X%200.3)
on simplification, we get
E(X) = 3.65
Joseph’s room would be bigger because, 7 X 8 is 56 and his brother’s room is 10 X 5 is 50

Answer:
The easiest method is to find the x-intercepts of the quadratic function by substituting y=0 in the function and solving it to find the possible values of x. The number of all possible values of x is the number of x-intercepts of the graph.
