Fill in the missing term in the equation

Y_Kistochka [10]

Answer:

x

Step-by-step explanation:

Let's simplify the LHS so it can be equated to the RHS.

$\frac{x}{x^{2} -4x+4} - \frac{x}{x^{2} -3x+2}$

$\frac{x}{(x-2)^{2} } - \frac{x}{(x-1)(x-2)}$

$\frac{x(x-1)-x(x-2)}{(x-2)^{2}(x-1)}$

$\frac{x^{2} -x-x^{2}+2x }{(x-2)^{2}(x-1)}$

$\frac{x}{(x-2)^{2}(x-1)}$

Hence, the missing term in the numerator of the answer is x

Two fair dice are tossed, and the up face on each die is recorded. Find the probability of observing each of the following event

Kamila [148]

Answer:

Step-by-step explanation:

When two fair dice are tossed sample space consists of 36 events

(1,1)....(6,6)

A_ The difference of numbers is 2 or less

Favorable outcomes = $(1,1) (1,2) (1,3) (2,1) (2,2)(2,3) (2,4) (3,1) (3,2) (3,3) (3,4) (3,5) (4,2) (4,3)(4,5) (4,6) (5,3) (5,4) (5,6)\\$

Hence Probability = $\frac{19}{36}$

B) A 4 does not appear on either die

Then we must not have these

$(4,1)(4,2)(4,3) (4,4) (4,5) (4,6)\\(1,4) (2,4) (3,4) (5,4) (6,4)$

Hence probability = $\frac{36-11}{36} =\frac{25}{36}$

C: The sum of numbers is 10 or more:

FAvourable outcomes are:

$(4,6) (5,5) (5,6) (6,5) (6,4)$

Probability = $\frac{5}{36}$
