Find p(y|b) from the information in the table.
a 5-column table has 4 rows. the first column has entries a, b, c, total. the second column is labeled x with entries 8, 6, 23, 37. the third column is labeled y with entries 80, 34, 56, 170. the fourth column is labeled z with entries 40, 45, 32, 117. the fifth column is labeled total with entries 128, 85, 111, 324.
to the nearest tenth, what is the value of p(y|b)?
0.2
0.3
0.4
0.5

0.4

Step-by-step explanation:

The table with correct formatting is attached in the image below.

We have to find P(Y | B). This is a conditional probability i.e. probability of Y given B.

The formula of conditional probability for two event A and B is:

So, for the given case, the formula would be:

P(Y ∩ B) indicates the probability of Y and B occurring together. Y and B occur together 34 times out of total of 324, so:

P(B) indicates the probability of occurrence of B. B occurs 85 times in a total of 324. So,

Using these values in the formula of conditional probability, we get:

Thus, the value of P(Y|B) is 0.4

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
