A bag containing alphabet blocks which are blue, green, and red blocks, is mixed thoroughly. In total, there are 9 blue blocks, 8 green blocks, and 9 red blocks. If 5 blocks are selected at random, what is the probability they will be red?
If 6 blocks are selected at random, what is the probability there will be an equal number of each color block?
Would it be unusual to draw 4 green blocks at random?
Since these are letter blocks, you decide to try to spell “CAT”. What is the probability that, without looking, these three blocks are all drawn in sequence?

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

the graph is negative for all real values of x where   -6 < x < -2.
