On the spinner, the probability of landing on black is 1/2 , and the probability of landing on red is 1/3. Create a probability
Margarita [4]

Answer:

1) p_i \geq 0 , \forall i

2)\sum_{i=1}^n P_i = 1, i =1,2,...,n

And for this case we have:

\frac{1}{2}+\frac{1}{6}= \frac{2}{3}

By the complement rule we can find the probability that the spinner land in a non black or red space:

p(N) = 1- \frac{1}{2} -\frac{1}{3}= \frac{1}{6}

And then the probability distribution would be:

Color      Red     Black    N

Prob.      1/3         1/2       1/6

Step-by-step explanation:

For this case we have two possible outcomes for the spinner experiment:

p(black) =\frac{1}{2}

p(red) = \frac{1}{3}

In order to have a probability distribution we need to satisfy two conditions:

1) p_i \geq 0 , \forall i

2)\sum_{i=1}^n P_i = 1, i =1,2,...,n

And for this case we have:

\frac{1}{2}+\frac{1}{6}= \frac{2}{3}

By the complement rule we can find the probability that the spinner land in a non black or red space:

p(N) = 1- \frac{1}{2} -\frac{1}{3}= \frac{1}{6}

And then the probability distribution would be:

Color      Red     Black    N

Prob.      1/3         1/2       1/6

Plz help me !!!! I’m not sure if it’s 20 !
vodka [1.7K]

Answer:

D) 20º

Step-by-step explanation:

if one angle is 70º, and the other is 90º, that means that the first two angles equal 160º. since all three interior angles of a triangle have to add up to 180º, the third angle must be 20º.

Trigonometry. please help​
koban [17]

Answer:

C) 3/5

Step-by-step explanation:

Have you heard of this way to memorize the trig ratios?

SOH-CAH-TOA  (Say it out loud so you remember it.)

It represents these ratios:

Sine = opposite side / hypotenuse

Cosine = adjacent side / hypotenuse

Tangent = opposite side / adjacent side

In this problem, cos C = adj / hyp = BC / AC = 24 / 40.

That simplifies to 3/5
