The median of the number of runs scored by a baseball team in its last 9 games is 7. Which of the following statements must be true? A) The team must have scored 10 runs in at least one of the games. B) The team must have scored 6 runs in at least one of the games. C) The team must have scored 7 runs in at least one of the games. D) None of the above choices must be true.

The answer is here:

D. None of the choices above must be true (Or it might be A.he team must have scored 10 runs in at least one of the games)

its nun of the above it should be 8

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
