Bonnie's truck has a fuel tank which holds 50 gallons and she typically drives 425 miles on a full tank. she has added a second tank which holds 30 gallons to figure how far she can go between fill ups now she multiplies 50 * 425 then divides by 30 to get 708 point three miles is this correct?

answer: no

step-by-step explanation:

the answer to the expression is 83

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
