two numbered 1 to 6 dice are thrown together and their scores are added. the probability that the sum will be 4 is?

natulia [17]

Answer:

$Pr = \frac{3}{36}$

Step-by-step explanation:

Given

2 number die

Required

P(Sum = 4)

The sample space of 2 die is:

$S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6), (2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)$

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

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

$n(S)= 36$

The pairs that adds up to 4 are:

$Sum(4) = \{(1,3), (2,2),(3,1)\}$

$n(Sum) =3$

So, the probability is:

$Pr = \frac{n(Sum)}{n(S)}$

$Pr = \frac{3}{36}$

Charlie must have had 11 rice cakes

You multiply 120 times 3 to get 360

then 800- 360 = 440

440 divided my 40 = 11

Which of the following methods would be the easiest to use to solve x2 + 5x – 6 = 0?

EastWind [94]

For me personally, the easiest way to do this is by isolating the x² term, and finding the square root of both sides. The hardest way (well actually, the longest way) would be to use the quadratic formula. It just complicates things unnecessarily.

6/42 in simplest form :

Divide both the nominator and the denominator by the HCF (highest common factor) : 6

6/42 = 6:6/42:6 = 1/7

Solve the equation. 4x + 1 + 2x = 61 6 10 10.3 11.8

poizon [28]

Answer:

x = 10

Step-by-step explanation:

=> 4x + 1 + 2x = 61

=> 6x = 61 - 1

=> 6x = 60

=> x = 60/6

=> x = 10

Hence the value of x is 10 .
