Find the probability giving brainlest
Gwar [14]

Answer:

0.33

Step-by-step explanation:

There are 6 sides on dice, therefore the sample space would be 6 (<em>the</em><em> </em><em>sample</em><em> </em><em>space</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>denominator</em>). We were asked to find the probability of getting a 1 or a 6. Since we were given 2 options 1 or 6, it therefore means that we are trying to find the probability of the dice rolling on 2 out of the 6 sides it has. Therefore the probability would be:

\frac{2}{6}  \: or \:  \frac{1}{3}

A third as a decimal is

How do you solve this
fiasKO [112]
(((x + y) / 3) + (1 / x)) / (5 + (15 / x))
The best way is to make it one fraction.
Multiply by ((3x/3x) / (3x/3x)) to remove the other fractions.
((x(x + y)) + 3(1)) / (5(3x) + 3(15))
(x^2 + xy + 3) / (15x + 45)
Then factor to simplify
(x^2 + xy + 3) / (3(x + 15))
