Robin, Steven, and John are comparing tree diagrams for rolling double sixes on two six-sided number cubes (6, 6). Robin thinks the probability is 1/36 based on the tree diagram they created. Steven disagrees and argues that the probability of rolling double sixes is 1/6. John counts twelve outcomes and claims the probability is 1/12. Who correctly found the probability of rolling double sixes using the tree diagram?
A: Robin because there are 36 outcomes and only one is (6, 6).
B: Steven because there are 6 outcomes and only one is (6, 6).
C: Steven because there are 36 outcomes and six of them are (6, 6).
D: John because there are 6 outcomes for each and only one is (6, 6).

whats the question?

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

answer: y = -2.5x - 15
