Kimane and a friend picked apples. Kimane picked 4 2/3 lbs and his friend picked 5 5/6 lbs. About how many more pounds of apples do they need to pick to have about 20 pounds of apples all together?

  9 1/2 pounds

Step-by-step explanation:

The total weight of apples picked so far is ...

  4 2/3 + 5 5/6 = (4 +5) +(4/6 +5/6) = 9 + 9/6 = 9 + 1 1/2 = 10 1/2

Then the weight of apples needed so the total is 20 pounds is ...

  20 -10 1/2 = (20 -10) -1/2 = 9 1/2

They need to pick about 9 1/2 more pounds of apples to have 20 pounds altogether.

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
