Studies have shown 14.5% of this particular model of car has power door lock malfunctions within the first 5,000 miles driven. The manufacturer is worried about triggering a national recall on their power door locks (resulting in millions of dollars of losses) if it is determined 15% or more of the owners report this issue within the first 5,000 miles the vehicle is driven. Determine the probability of triggering a recall on the power door locks based on a random sample of 1,000 customers having driven the car within the first 5,000 miles.

you cant answer this dummy

step-by-step explanation:

practice. practice. practice.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

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
