A bag contains blue and pink balls. There are 8 more blue balls than pink balls. Identify the expression that represents the pro

bability that a person will pick a blue ball first and then a pink ball without replacement. Then find the probability of someone picking a blue ball and then a pink ball if the bag originally contains 5 pink balls. Round to the nearest hundredth.

Let 
b---> the original amount of blue balls in the bag
p---> the original amount of pink balls in the bag

we know that
b=8+p
p=5
so
b=8+5----> b=13

step 1
Find the total of balls originally in the bag
total =13+5-----> 18

step 2
find <span>the probability that a person will pick a blue ball first
</span>Find P(b)
P (b)=13/18

step 3
Find the probability that a person will pick a pink ball second <span>without replacement
the total of balls now is (18-1)-------> 17
P(p)=5/17

step 4
Find </span><span>the probability that a person will pick a blue ball first and then a pink ball without replacement 
</span>(13/18)*(5/17)-----> (13*5)/(18*17)------> 65/306-----> 0.21

the answer is
0.21

Answer:

0.212

Step-by-step explanation:

Thinking process:

Let the b  = the original blue balls in the bag

and p = the original number of pink balls in the bag

Thus,

the number of blue balls is more than pik balls, therefore:

b = 8 + p

and p = 5

therefore, b = 8 + 5

                    = 13

The total number of balls = b + p

                                           = 5 + 13

                                           = 18

Probability of person picking a blue ball, P(b) = \frac{13}{18}

The probability that a person picks a pink ball without replacement = 18 - 1

                                                                                                                 = 17

= \frac{5}{17}

The probability that a person will pick a blue ball and pick ball without replacement =

Answer:

x = 17

Step-by-step explanation:

A triangle's sum is 180 degrees, hence

6x + 10 + x + 17 + 4x - 34 = 180.

11x + 10 + 17 - 34 = 180

11x - 7 = 180

11x = 187

x = 17

hope this helps and is right!! p.s. i really need brainliest :)

1) Which of the following has a probability of 0?
melamori03 [73]

Answer:

3. rolling a sum of 20 with two standard dice

Step-by-step explanation:

If something has a probability of 0 then there is no chance of it happening

A standard die goes up to 6. The max sum you can get by rolling two dice would be 12 as 6 + 6 = 12. So you have no chance of rolling a sum of 20 with two standard dice therefore the probability would be 0.
