Cody buys a soda that offers another soda free if he is lucky. The cap reads '1 in 6 wins!', meaning that each soda has a 1/6 pr

creativ13 [48]

Answer: 0.26

Step-by-step explanation:

Binomial probability formula :-

$P(X=x)=^nC_x\ p^x\ (1-p)^{n-x}$ , where P(x) is the probability of getting success in x trials , n is total number of trials and p is the probability of getting success in each trial.

Given : The probability of winning = $\dfrac{1}{6}$

Let X be the random variable that represents the number of sodas.

Since he is guaranteed that he will win one soda .

If Cody buys 6 sodas, then the probability that he will win at least one more soda will be :

$P(x\geq2 )=1-(P(0)+P(1))\\\\=1-(^6C_0\ (\dfrac{1}{6})^0\ (1-\dfrac{1}{6})^{6-0}+^6C_1\ (\dfrac{1}{6})^1\ (1-\dfrac{1}{6})^{6-1})\\\\=1-((\dfrac{5}{6})^6+(\dfrac{5}{6})^5)\approx0.26$

Hence, the true probability he will win at least one more soda =0.26

Alice, Bob and Kevin

7 different Flavors:

Chocolate

Vanillla

mint chip

strawberry

cookie dough

banana

caramel

The order of the 9 scoops does not matter.

_ _ _ _

a) How many ways can she choose her 9 scoops so she gets at least 1 scoop of each flavor?

Since there are 7 flavors, and she wants at least one of each then we have:

$C=\frac{9!}{7!2!}\text{ =3}6$

Alice has 36 possibilites of choosing

b) Bob

Since Bob can't eat too much he can't do no more than 4

$C\text{ =}\frac{9!}{4!5!}=126$

Bob has 126 possibilities of making his choice.

c) Kevin

3 scoups of banana or 3 scoups of strawberries.

Considering He wants 9 scoups.

$C=\frac{9!}{6!3!}=84$

Kevin has 84 possibilities for banana or strawberries

Find the height of X. Having a hard time figuring this out

Delvig [45]

Use the pythagorean theorem:
$a^2 +b^2 = c^2$

where c is the hypotenuse of the triangle.

$x^2 +12^2 = 14^2 \\ \\ x^2 +144 = 196 \\ \\ x^2 = 52 \\ \\ x = \sqrt{52} = 2 \sqrt{13}$
