Question 1
Leslie has three quarters and she dropped all three of them what is the probability that all three quarters will land on
Heads?

The probability to get heads on all three quarters is 1/8.

Step-by-step explanation:

Given data :

It can be determined that :

The total number of possible outcomes you can get from the three quarters with two sides = 2³ ⇒ 2×2×2 ⇒ 8 total outcomes.

If she drops all three of the quarters in the same time, there will be a total of 8 different outcomes.

These 8 outcomes include (T,T,T), (H,T,T), (H,H,T), (T,H,H), (T,T,H), (T,H,T), (H,H,T), (H,H,H).

From the above shown different possible outcomes, you need to find the probability that all three quarters will land on  Heads.

Probability(3 heads)= No. of outcomes with 3 heads / Total no.of  outcomes

We know that,

⇒ P( 3 heads ) = 1/8

The probability to get heads on all three quarters is 1/8.

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
