what fraction of the bag are red and yellow?

17/30 of the bag is red and yellow.

Step-by-step explanation:

Change the denominator on both fractions to add them. The denominator has to be changed to 30.

Multiply 4/15 by 2.           Multiply 3/10 by 3.

8/30                                  9/30

Add both fractions together.

8/30 + 9/30 = 17/30

17/30 of the bag is red and yellow.

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
