At a highschool, 90% of the students take physics and 35% of the students take both physics and statistics. What is the probability that a student that is taking physics is also taking statistics

38.89% probability that a student that is taking Physics is also taking Statistics

Step-by-step explanation:

Conditional probability formula:

Two events, A and B.

In which

P(B|A) is the probability of B happening, given that A has happened.

is the probability of these two events happening.

P(A) is the probability of A happening.

In this problem, we have that:

A: physics

B: statistics.

90% of the students take Physics

This means that

35% of the students take both Physics and Statistics.

This means that

So

38.89% probability that a student that is taking Physics is also taking Statistics

i believe that is true.

step-by-step explanation:

hope my answer has you if not i'm sorry.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
