Question

a number is chosen at random from the numbers -3,-2,-1,0,1,2,3. what will be the probability that square of this number is less than or equal to 1

Answer 1

Hey sup!

Favorable outcome={-1,0,1}=3.
Total outcome={-3,-2,-1,0,1,2}=6.

So probability that square of the number is less than or equal to 1 = favorable/total.
=3/6.
=1/2.

Hope it helps.

Answer 2

Total outcome = 7
Possible outcome = 3

P ( E ) = Possible outcome/total outcome

P ( E ) = 3 /7
