Answer:

Step-by-step explanation:

3x^4 - 9x^2 - 12 = 0

x^4 - 3x^2 - 4 = 0

x^2 = [3 ± √(3^2-4(1)(-4))]/[2(1)] = [3 ± 5]/2 = 4,-1

f(x) = 3(x^2-4)(x^2+1) = 3(x+2)(x-2)(x^2+1)

The probability of a sporting event being cancelled due to rain or lightning is 6/25

<h3>What is Probability?</h3>

This is the likelihood or chance that an event will occur.

Probability = Expected/Total

Given the following

Pr(rain) = 3/5
Pr (lightening) = 2/5

The probability of a sporting event being canceled due to rain or lightning = 3/5 * 2/5

The probability of a sporting event being canceled due to rain or lightning = 6/25

Hence the probability of a sporting event being cancelled due to rain or lightning is 6/25
