Question

If a number x is chosen at random from the numbers -2,-1,0,1,2. What is the probability that x^2 is lesser than 2

Answer 1

Answer:

Step-by-step explanation:

x^2 in this case is always less than 4.

So probability =5/5

=1

Answer 2

we have options to choose total 5 numbers

so total outcome is 5

now 2 and - 2 are not valid for given information that x² < 2

so we can select only remaining 3 numbers

so

P(A) = 3 / 5
