1.	If one number is selected from first 70 natural numbers, find the probability that the number is a solution of x^2 + 2x > 4....Plz don't spam or I curse you for 13 Years of Badluck.
Answer» Step-by-step explanation: Given If one NUMBER is selected from first 70 natural numbers, find the PROBABILITY that the number is a solution of x^2 + 2x > 4 Now probability is given by probability = number of FAVOURABLE outcomes / total number of possible outcomes. Now a number is selected at random from first natural numbers. So we get total number of outcomes will be 70 Favourable outcomes will be So x^2 + 2x > 4 Now TAKING 1 we get 1^2 + 2 (1) = 3 < 4 2^2 + 2(2) = 8 > 4 So all other numbers up to 70 will be greater than 4. So we have 70 – 1 = 69 So total number of favourable outcomes will be 69 Therefore probability will be 69 / 70 Reference link will be brainly.in/question/8619616

Step-by-step explanation:

Given If one NUMBER is selected from first 70 natural numbers, find the PROBABILITY that the number is a solution of x^2 + 2x > 4

Now probability is given by probability = number of FAVOURABLE outcomes / total number of possible outcomes.
Now a number is selected at random from first natural numbers.
So we get total number of outcomes will be 70
Favourable outcomes will be
So x^2 + 2x > 4
Now TAKING 1 we get 1^2 + 2 (1) = 3 < 4
2^2 + 2(2) = 8 > 4
So all other numbers up to 70 will be greater than 4. So we have 70 – 1 = 69
So total number of favourable outcomes will be 69
Therefore probability will be 69 / 70
