What is the value of p in the equation? 1/4(8-4p) +2p=12a. -20b. -2c. 5d. 10

1/4(8-4p) +2p = 12

Distribute the 1/4

2 - p + 2p = 12

Combine the p's

2 + p = 12

Subtract 2 from each side

2 - 2 + p = 12 - 2

0 + p = 10

p = 10

The answer is D. 10

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
