- A number x is chosen at random from the numbers -2, -1, 0 , 1, 2.
Question 1:
A number x is chosen at random from the numbers -2, -1, 0 , 1, 2. Then the probability that x^2 < 2 is? A. 1/5
B. 2/5
C. 3/5
Feedback We have 5 numbers −2,−1,0,1,2
Whose squares are 4,1,0,1,4
So square of 3 numbers is less than 2
Therefore Probability is: P (x^2 < 2) = 3/5
