Lily has 8 dog toys that are red. One third of all her dog toys are red.
How many dog toys does Lily have?
Complete the explanation.
First, draw
circles to show
equal parts.
Next, draw
toys in
circle since
circle represents the number of red toys.
Last, draw
toys in each of the remaining circles. Find the total number of toys.
So, Lily has
dog toys.

She has 24 dog toys

Step-by-step explanation:

8x3=24

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

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
