Hot dog buns come in boxes of 8. On Friday's game, the chef uses 2 1/6 boxes of hotdog buns. On Saturdays game, the chief uses 1 4/6 boxes of hotdog buns. How many boxes of hotdog buns did the chef use altogether?

3 and 5/6

We know this because it says the chef uses 2 1/6 boxes on one day and 1 4/6 on the other.

2 + 1 = 3

1/6 + 4/6 = 5/6 (cannot be simplified)

Put them together = 3 and 5/6

answer: 1, 3 and 5 are correct

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
