Joy is giving ice cream cones to some children at a carnival. She has 8 chocolate ice cream cones, 10 vanilla ice cream cones, a

nd 6 strawberry ice cream cones. If Joy selects an ice cream cone randomly without looking, what is the probability that she will give a chocolate ice cream cone to the first child and then a vanilla ice cream cone to the second child? 8 over 24 plus 10 over 24 is equal to 18 over 24 8 over 24 plus 10 over 23 is equal to 424 over 552 8 over 24 multiplied by 10 over 23 is equal to 80 over 552 8 over 24 multiplied by 10 over 24 is equal to 80 over 576

[6+4=10 points] Problem 2. Suppose that there are k people in a party with the following PMF: • k = 5 with probability 1 4 • k =
kirza4 [7]

Answer:

1). 0.903547

2). 0.275617

Step-by-step explanation:

It is given :

K people in a party with the following :

i). k = 5 with the probability of $\frac{1}{4}$

ii). k = 10 with the probability of $\frac{1}{4}$

iii). k = 10 with the probability $\frac{1}{2}$

So the probability of at least two person out of the 'n' born people in same month is  = 1 - P (none of the n born in the same month)

= 1 - P (choosing the n different months out of 365 days) = 1-\frac{_{n}^{12}\textrm{P}}{12^2}

1). Hence P(at least 2 born in the same month)=P(k=5 and at least 2 born in the same month)+P(k=10 and at least 2 born in the same month)+P(k=15 and at least 2 born in the same month)

= \frac{1}{4}\times (1-\frac{_{5}^{12}\textrm{P}}{12^5})+\frac{1}{4}\times (1-\frac{_{10}^{12}\textrm{P}}{12^{10}})+\frac{1}{2}\times (1-\frac{_{15}^{12}\textrm{P}}{12^{15}})

= 0.25 \times 0.618056 + 0.25 \times 0.996132 + 0.5 \times 1

= 0.903547

2).P( k = 10|at least 2 share their birthday in same month)

=P(k=10 and at least 2 born in the same month)/P(at least 2 share their birthday in same month)

= $0.25 \times \frac{0.996132}{0.903547}$

= 0.0.275617

Match each as either linear or non-linear. HELP​
Virty [35]

Answer:

<u>Linear</u>

y=-x

y  =  \frac{x}{9}

-  \frac{2}{3}x + 3y = 1

<u>Non linear</u>

y =  \frac{4}{x}

\frac{2}{y}  = x

{x}^{2}  +  {y}^{2}  = 1

Step-by-step explanation:

Linear equations have the highest degree to be 1.

Therefore y=-x is linear.

y =  \frac{x}{9}  \: is \: also \: linear.

y =  \frac{4}{x}  \implies \: xy = 4

The degree of this equation is 2.

It is non-linear

-  \frac{2}{3}x + 3y = 1

is also linear.

\frac{2}{y}  = x \implies \: xy = 2....non - linear

{x}^{2}  +  {y}^{2}  = 1.....non - linear
