Caitlyn had 72 more dolls than her sister, ashley.
caitlyn also found that she had thrice the number of dolls as her sister.
what is the product of the 2 sisters' dolls?

3888

Step-by-step explanation:

Let Caitlyn be C and Ashley be A.

By the problem,

C=72+A

C=3A

So, 2A=72

therefore Ashley has 36 dolls

and Caitlyn has 108 dolls

and the photo of the two sisters' dolls is 3888

3888.

Step-by-step explanation:

y = x + 72   where y = number of Caitlyns dolls and x is the number of Ashleys.

Also y = 3x

So we substitute y = 3x in the first equation to get:

3x = x + 72

2x = 72

x = 36 = total od Ashley's dolls.

So Caitlyn has 36 + 72 = 108 dolls.

Product = 108 * 36 =  3888.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
