Question

If a number x is chosen at random from the numbers -2,-1, 0, 1,2.what is the probability that x2<2.

Answer 1

Do you mean 2x<2 or

X <2 or do you mean x²<2

Explanation:

If your question is X²<2

Then

Total outcomes=5

Possible outcomes=3(-1,0,1)

Probability of x²<2=3/5

If your question means probability of2x<2

Then

Total outcomes=5

Possible outcomes=3 (-2,-1,0)

Probability of 2x<2=3/5

If your question means x< 2

Then

Total outcomes=5

Possible outcomes=4 (-2,-1,0,1)

Probability of x <2 =4/5
