Answer:

I dont know how many pounds are in an ounce but I'll give you an explanation using kilograms and grams as an example and I'll talk you through it

Step-by-step explanation:

there are 1000 grams(g) in a kilograms (kg) just so you know

let's say I have a 13 g box of cereal for $3.99.

I do a ratio to work out 1 kg

13 g : $3.99

1000g : x

In your case your going to write

13 ounces : $3.99

[here write how many

ounces are in a pound] : x

to find x you 1st have to take the 2 numbers you do know and divide them

so in my example I do 1000g÷13 g = 76

then I take 76.92 and I multiply it by the other side

$3.99 x 76.92 = 306.91

for me 1kg of cereal is worth $306.91

all you need to do is replace my 1 kg with how many ounces are in a pound

Player V and Player M have competed against each other many times. Historical data show that each player is equally likely to wi

Helen [10]

Answer:

0.46 (46%)

Step-by-step explanation:

We have the following data:

- Probability that player V wins the first set:

$p(1)=0.50$

(because the text says the two players are equally likely to win the first set)

- Probability that player V wins the 2nd set if he has won the 1st set:

$p(2|1)=0.60$

So, the probability that player V wins the first 2 sets is:

$p(12)=p(1)\cdot p(2|1)=(0.50)(0.60)=0.30$ (1)

Instead, the probability that player V loses the 2nd set if he has won the 1st set is 0.40 (=1-0.60), so

$p(2^c|1)=0.40$

So, the probabiity that player V winse the 1st set but loses the 2nd set is

$p(12^c)=p(1)\cdot p(2^c|1)=(0.50)(0.40)=0.20$ (2)

Also, we have:

- Probability that player V loses the 1st set:

$p(1^c)=0.50$

- Probability that she will lose the 2nd set in this case is 0.70, it means that the probability that she will win the 2nd set if she lost the 1st set is 0.30, so:

$p(2|1^c)=0.30$
